Either relatively new (2007) or upcoming.
For example, I personally find these exciting:
・Blu-Ray (not new)
・LED
・OLED
・USB 3.0
・Windows 7
・Wireless N
・3D Stereoscopic Viewing
・Zune HD (not so much anymore)
I’m bound to be missing a few here.
Whoever tells me the ones that I find are most interesting gets their answer picked.
Software counts.
Also, I also already know of Microsoft Surface, just in case anyone tries to include that.
