I can confirm that my think outside stowaway BT keyboard i bought almost 7yrs ago is working fine with my GTab. I have now done 3 full charges so far & it on average use, about 4hrs of surfing & checking emails i got going for 46hrs before it ask me to charge. Obviously i keep my 3G & Wifi off when not surfing or checking mail. I'm expecting in a couple of weeks once the battery is well conditioned to get about at least 8hrs non-stop surfing. Loving it big time 

cheers
