Have the 1st Transformer. The week before last it just stopped charging. Tested the charger on the keyboard dock, and it charged ok. Connected the Trans to the dock, and charged it using that work-around. Once it was fully charged, I was able to download and update to the latest firmware. Once completed, the Transformer now charges properly on its own. If I hadn't purchased the $150 accessory, I wouldn't have a Transformer right now. It'd be dead and waiting God only knows how long for a RMA.
I hope they have the bugs worked out. More complicated hardware w/o lessons learned = wait and see 3 months after release.
