The Thunderbolt'd battery may be underpowered... But the phone itself is not. It flies.

Very true! I'm hoping HTC/Verizon will be tweaking the firmware shortly and addressing the battery issue. I already have a portable battery charger in case I'm not near an outlet/usb to charge up. It's slightly larger than the battery (Kensington). I may get another battery to keep on hand to swap out, but I'd rather keep opening the battery door to a minimum ( the one design I find lacking on the TB!) and may just stick with the portable charger.
