One of the reasons I'm a bit wary of buying dedicated stands for my tablet and smartphone is that technology seems to evolve quite quickly, and there's no telling when your devices will no longer fit in them. Hacking one seems like a sensible option, since it's low cost, you get to customize the stand to your liking, and you can always modify it to fit a newer device.
After moving into a new place, Peter from Sweden had a bunch of spare IKEA Ribba picture ledges ($9.99). He decided to use one as the basis for a tablet/smartphone stand that he could use on his desktop.
For the full instructions, check out Peter's post about the hack on IKEA Hackers.
With the same Ribba picture ledge, you'd probably have enough material for a few different stands, since they measure about 21 inches in length. IKEA Ribba ledges can also be used to wrangle your cords.
This would work in smaller pieces for say, an iPhone bed-side stand as well.There are plenty of options available for DIY stands. Check out this post for more ideas. If you're not into DIY, then you can peruse Etsy. They've got many different stands that might suit your fancy.
