Apparently what a geek wants is to coat all her gadgets in gels. They're ubiquitous among BlackBerrys and iPhones, and I've seen them for Mighty Mice (mouses?), and now: Silicone Sleeves for the Wii Fit Balance Board ($20).
I have a love/hate relationship with gel cases; while they're great at protecting your gear (especially in the case of a fall), the light ones tend to get discolored and murky looking, and they are lint-magnets (ever leave your gel-covered BlackBerry in your handbag with a floating tissue? Oy vey). I also haven't noticed that my balance board needs protecting, but the silicone might make a more comfortable surface underfoot. What do you think?
