You waited patiently. For two years, you watched as the iPad became more powerful and its software library exploded. Now the third generation iPad is here, and you finally made the leap. Given the mountain of potential accessories, apps, and additions available, we've put together a few tips for first-time iPad owners like yourself.
There are so many accessories available - where do I start?
Buying an iPad for the first time presents an interesting dilemma. It may be unclear exactly how you're going to use your tablet over time. Perhaps you expect to only consume content - watch movies, read news and emails, etc - only to find that you love using it to create digital artwork. You might buy a physical keyboard if you anticipate a lot of typing, but what if the dictation feature works wonders for you?
The iPad is an incredibly versatile device, and your expectations for use may be turned upside down after just a week of ownership. For this reason, I recommend holding off on buying highly specialized accessories, such as wall mounts, cases with built-in keyboards, and specific adapter cables.
There are a few "safe bets" to make when you first purchase. For basic protection, Apple's Smart Covers are a great start. They shield the screen, prop up the iPad with a simple fold, add minimal bulk, and pop on and off with ease. A snap-on shell (like Belkin's Snap Shield) is a sound choice for protecting the iPad's rear - just remember to find an iPad 3-compatible shell, as the dimensions vary slightly from the previous model, and these cases fit snugly. A simple sleeve can add protection in a messenger bag or backpack. I'm a particular fan of these handmade wool felt sleeves by artist Angie Davis, aka Byrd & Belle.

These protective products are an excellent place to start. Once you've become better acquainted with your iPad, venture out and find the specialized accessories that complement your workflow. There are some truly wonderful products out there, such as Twelve South's PlugBug (which expands your MacBook power adapter to charge your iPad) and Incase's Origami Workstation (an Apple Wireless Keyboard carrying case that folds to become an iPad stand as well).
Is AppleCare worth it?
Your iPad comes with a year of hardware coverage and 90 days of phone support, both of which can be extended to two years by purchasing AppleCare. In the past, this program didn't cover accidental damage, leaving accident-prone customers with hefty repair bills. With the new iPad, however, Apple has implemented AppleCare+, an expanded service that debuted with the iPhone 4S last fall. AppleCare+ costs $99 up front, and users are covered for up to two "incidents of accidental damage", each of which is subject to a $49 service fee. While this may sound pricey, remember that without AppleCare+, consecutively replacing two accidentally-damaged tablets could run you over $1,000. If you're notoriously rough on your tech, this may be a sound investment.
AppleCare+ must be bought along with your iPad or within 30 days of purchase. To do the latter, you must make an appointment at your local Apple Store so that a Genius can inspect your iPad. This prevents folks from buying AppleCare+ after they've already damaged their device. Once your tablet passes inspection, you'll be able to buy AppleCare+, which will activate immediately.
What's the best way to charge my iPad?
One look within an iPad and you'll see that it's basically a massive battery attached to a screen. To power the updated display, beefy processor, and 4G LTE chip, Apple doubled the battery capacity over last year's model. The best way to charge your iPad is with the included 10 watt power adapter. The high-power USB ports found in some recent computers can provide a decent alternative, but the speed won't compare to the 10 watt adapter. The same goes for an iPhone power adapter - it'll work, but slowly. If you're shopping for a third-party charger, make sure it specifically mentions the iPad, as many iPhone or iPod specific chargers won't give you the juice you need for an effective charge. For more information about the iPad's battery and how to get the most out of it, check out Apple's informational page.

Remember: More Pixels, More Megabytes
The new iPad's marquee feature is its Retina display, which boasts 3.1 million pixels - four times that of its predecessor. What you might not consider is that with such a jump in resolution comes a jump in file sizes. Every icon, texture, photo, video, illustration, and animation must be scaled appropriately, making every app larger in turn. For example, Apple's presentation app Keynote jumped from 115MB to 327MB to support the 9.7" Retina display. Graphically intense apps such as games are most likely to push the envelope.
Depending on your iPad's capacity and the kind of apps you use, this may not become an issue for you. However, if you're concerned about space when buying an app, you can check it's size in it's App Store listing, right after the version field. To learn about the apps you've already downloaded, open up the Settings app, then tap through to General > Usage, where you'll find a breakdown of your iPad's occupied memory. It's a handy way to keep track of your available space!

Great suggestions!
It's like you knew or something! Just bought a refurbished ipad 2, expecting it to come in the mail tomorrow.
If i want to know all about the ipad, i read a blog about electronic gadgets... Why are you doing product placement for ipads that have nothing to do with home decor?
I learned with my iPod Touch not to bother buying non-Apple chargers. The ones that work only work some of the time.
Dropping the cash to buy an ipad in the first place was a challenge for me mentally, and the thought of buying apps and accessories had me cringing. I've had my iPad 2 since April, and the only accessory you really "need" right away is a case/cover. I bought a smart cover and love it.
Since I'm in grad school, I do lots of typing, so I decided to test drive the onscreen keyboard in my summer class before dropping money on a wireless keyboard. It was fine, but inconvenient. If you plan on doing a lot of typing, go ahead and get yourself a keyboard (and I second the Origami Workstation--I love mine so much), but if you're not planning on doing much word processing, I wouldn't bother. The only other gadget I'm considering buying is a stylus, but I've been putting it off because I'm not sure I'll use it enough to make it worth it.
The rest of my attention has focused on apps, mostly for productivity and reading. iTunes has some pretty good curated lists of apps for new users, and there are lots of reviews for most of them. I'd say start with some of the free apps and see what you end up using the iPad for. Once you've figured that out, start looking into paying for apps that will offer more/better functionality for what you actually do.
Hope that helps.
Argh! With the it's! Twice in one clause! Looks four times as awful on the new screen :P
I bought a Belkin stand with a stylus to use with my recipe books. Keeps the screen clean when I cook. I really like my ipad.
For iPads and iPhones, I was told by Apple store employees that Applecare could be purchased up to a year after the purchase. But Applecare is awesome and worth every cent for any Apple product.
I think you should have included the fact that for people who struggle to adapt and understand how the iPad works, Apple runs instructional courses.
The Adonit JotPro is an amazing stylus! I am now able to properly use my iPad as a sketch book for work. I was cynical about the smart cover but some black leather smart covers were priced up incorrectly in a electrical store, and by law they have to sell at the marked price, so I snapped it up and I love it! Then ordered a clear back cover off Amazon for a few quid!
Being totally new to the world of iPads (but salivating over the thought of using one)...
1. What kind of word processing and spreadsheet software do people use on the iPad? I don't want to do a LOT of docs, but basic home budgets, etc.
2. Is the iCloud worth investing in to store docs?
3. Is the Apple keyboard the 'one' to go with?
4. While I'm sure the leather Smart Cover is all around better, does the plastic one hold up well?
I still have my original iPad 1. I love it. Still. I loved mine so much I made a ton of iPad covers, kept some and gave the rest away to new iPad owners.
It is fabulous for reading. Fabulous for writing. Not bad at all for drawing.
I LIKE the fact that I don't have millions of screens open at once.
The Apps are fun - stick to the free ones to begin with, and read reviews (outside the App Store) before buying.
And ENJOY
@GIRLWHOWRITES, You can wait for a year to buy the regular AppleCare ($69). AppleCare+ covers accidental damage and costs slightly more ($99).
@HEATHERMICHELLE, Apple's own Pages and Numbers works great. For minimalist environment, I recommend iA Writer. iCloud works best for these apps since you don't have to actively save documents each time you edit them. Of course, if you use graphic-heavy document, you may have to shell out for additional storage but it's the same with DropBox. There are several keyboard options you can explore. Finally, I use a regular Smart Cover and it works well; leather is more durable and stylish though.
I've used our smart cover twice since getting our iPad. For me, a waste of money. On the other hand, our Griffin A-stand has been great!
