this is a nice Tab as it has 2 USB ports and a removable battery (no other decent Tab has a removable battery)
neither do they need them. by the time ur battery is used enough to not last a couple of hours, your tablet is going to be obsolete. and these things go for days with moderate usage unless you're on it for several hours straight. chances are, you probably have it charging before you really run out of battery. seriously, even if you're on the longest flight to somewhere, say it was 20 hrs maybe? how long do you think you will be on ur tablet using it during that flight?
carrying an extra battery for this thing around vs. having a charger handy
id prefer the latter any day and save me couple bucks from buying an extra battery, as well.
exactly why the removable battery did nothing to contribute to this tabs selling point.
