I suffer from sensory overload: too many things impinging on my consciousness too much of the time. When I look something up on Wikipedia, I don't like to be distracted with things like email notifications, cell phone rings, etc. and then lose my focus. Along comes the WikiReader, enabling me to do just that, and access Wikipedia whenever I want to. It's reasonably priced and best of all, there's no monthly fee, no Internet connection needed. I am so sick of gadgets that I really don't need. This is something I do need, and enjoy using, too. It's easy for me to rationalize spending $99 for it.
Yes, Wikipedia is available on the iPhone and the iPod Touch, but my phone rings, I get distracted, and the somewhat stressful pace continues. With the WikiReader I can tune out the distractions and relax while indulging my curiosity, satisfying my appetite for knowledge and wikifacts. For me it's a form of focused attention, meditation. And it's a fun learning experience, too. It's portable, unlike my desktop computer. Unlike a laptop, it fits in my purse or pocket, I can take it where ever I go. I can even sit and soak in knowledge as I soak in the bathtub. It's great on an airplane when I'm sitting next to someone I'd rather not converse with.
It's straightforward enough that I can use it right away, and it bridges the tech gap between my kids and me. What a gift!
