You could always try Acer A510w , It as 3G, wifi, usb, micro sd, and even hdmi output, ( wife plays Angry Birds on it hooked up to a 42 hd tv) and is android 2.3, with upgrade to 3.0 and soon 4.0 Ice cream sandwich, It's a 10 inch pad with gorilla glass and solid build. I've had mine since September and been very happy with it. Also you can install a mod android os.
