I've ordered a Playbook instead - preferred the screen when I tested in the shop - speakers seem better and the audio chipset (Wolfson WM8993) is meant to be good
much cheaper, but I'm going to use for only audio and video playback, no apps etc
My Nexus 7 (16GB) is generally smoother and more responsive than my playbook (64GB). The playbook is more solidly built though, my son (5 yrs old) has dropped his a few times now (once onto slabs from about 2 feet). Granted, the incipio feather case took the impact, but the playbook is fine!
