I love my Transformer so much. The hardware is awesome, works a treat. My use is to replace the main computer in the living room (getting rid of wires because of baby starting crawling very soon), which it is perfect for. The keyboard dock makes it usable to write longer emails/documents when needed, and it's undocked most of the time for couch surfing, and couch gaming.
And it has accepted any peripherals I've thrown at it (mouse, camera, SD card...)
I'll have to agree with that. This is my first Android device, but coming from a Linux/Maemo/Symbian, it's kinda weird to adjust to the multitasking (where is the exit button?!?). Another thing I'm missing is printing from the browser, looks like there is only 1 app for my printer to print photos only.
