There's no 360 degree look-around.
I've got the Acer Iconia Tab A500 and it's got a host USB port (for connecting mice/keyboards/external storage) and a mini USB port for connecting to a PC (no PC charging, though....thought that was strange). It also has a mini HDMI connector and a microSD slot for installing up to a 32GB card.
My wife is an iOS lemming, so, she just received her iPad2 today. Ordered from the Apple Store and it shipped from China along with the "cover"! CHINA!!! Funny, though, the return address says California.
