CES 2013 - I got a chance to go hands on with MSI's newly announced S20 slider and I'm pretty impressed. It's light, yet it is supposed to get at least 5 hours of battery life, all while featuring a full Intel Core experience. I do have one qualm with it though.
It features a keyboard when the screen is slid back. It's great and would be exactly what I'm looking for in a tablet. However, if you touch into a text box while the screen is slid back, meaning the keyboard is exposed and usable, the on-screen keyboard pops up. It's minor, but would definitely annoy me.
Otherwise, the thing is pretty awesome.
