vadsamoht has a good point, though I think it will be awhile until I see the need for a hub. As soon as there is something cool that catches my interest I will start looking for one.
I'm unlikely to buy memory sticks, I trust Newegg and Amazon.com to get me good prices on brands I've come to trust so am unlikely to venture further. Besides, it's difficult to compete with them for prices/warranty anyways.
To support members of the community, and it could be more convenient then to search for what few are offered at my usual suspect websites (Amazon, mostly) things like Micro fiber cleaning clothes would be nice. Replacement stylii might be worthwhile as well, but along with parts that's a long term thing rather than an immediate interest since I've been good about not losing/breaking things for some time.
Finally, while I didn't tick the box I might be interested in a custom paint job. It's unlikely, since I'm generally quite content with a simple muted tone, but if you get some decent talent I can't say I wouldn't at least take a look at samples/mock-ups.
