Well as I mentioned the feel of the Playbook is great, ideal stereo speaker location on front of the device, best in its class audio.
Standard mini usb synch and power, so no propriety cable nonsense. Also has a mini HDMI port, not tested yet.
One minor issue it wakes from sleep mode fast enough, but boot up from cold takes a minute, which is annoying.
The built in office app Docs to Go is quite good, nice interface and speedy.
The built in file manager is very good, a clean interface and fast. Much better than any in the android market.
The rear camera is 5 mega pixel and ok, but no flash, (but neither does the iPad), the front camera is high quality for video chat.
The new calendar app is well done and has nice Facebook integration, i.e. tells you the birthdays of your friends and allows you to quickly post a Happy Birthday on their Facebook.
