I'm pretty excited for the Microsoft Surface, purely because it looks like it'll be great competition to the iPad.
Microsoft really showed us what a "Smart Cover" should really be, by including a keyboard right into the screen cover for the tablet. The design of it is exceptional too, very different from the iPad and it has a lot more connectivity options.
This new video shows off how much you can do with the Surface and it's pretty impressive. It's great to see that there is a HD port, USB port and a MicroSD card slot - these options alone can be very inciting for people who want a productive tablet.
