Rather than dying after 2-3 years, I think a bigger concern is when the battery is faulty before then; how good is the service of the manufacturer/distributer/reseller of replacing the battery under warranty.. and even do they offer that service (even for a fee) if it's not under warranty?
Removable batteries take away this concern and I'm all for them. Always tried to get them for my phone, but then my phone used up power very quickly. I don't think I really need a spare battery power-wise for an ebook reader
