I'll chime in to agree with Dan here.

I understand why on phones, microsd is perhaps a "necessity" but why on tablets? Surely, it should be much easier (and cheaper?) to put a full size sd card slot on a tablet. Heck my N800 has 2.

A full size usb port would make adding peripherals (keyboard, mouse, storage) so much easier. Again, as most tablets are using the same hardware as phones, it should be easy to find space for full size ports.

I'd rather see ports like those than proprietary dock connectors (for docks that never appear or are hard to find) or even video out. I just don't see much use for video out for at least this generation of devices.
