Try updating the firmware!
I've had a 16Gb Transformer from mid-May and when I received the unit there was already a firmware update waiting for me, closely followed by another one a couple of days later and then the big update to Honeycombe 3.1 at the start of June. Asus if nothing else can't be moaned at for not fixing issues. Firmware updates have fixed camera and performance issues as well sorting out issues with the keyboard that people have been experiencing - most of which seem to have been pretty much iradicated now.
My only real disappointment with the Transformer is the lack of apps available for Honeycomb - which can't really be blamed on Asus. I have noticed over the last week or so there have been a trickle (def. not a glut) of Honeycomb compatible apps and games being released which can only be a good thing. Overal I'm pretty happy with mine (as long as the apps keep coming)
