I have been shopping for days for an Android tablet, and have hit what appears to be a complete unknown quantity: battery replacement. Apple has publicly posted that they will send a replacement tablet for a service fee of $99. As far as I can tell, the other manufacturers that I am considering (Acer, Asus, Motorola) have thought about how to handle battery replacement. I contacted Acer and Asus customer service, and they confirmed that it can't be replaced by the user, but they didn't have any answer as to how much it may cost to get the battery replaced. Have any of you looked into this? Are you concerned?
