The first personal computer actually made by Microsoft! That's history. They've made mice, and X-boxes, but never desktops, laptops, or tablets.
What impressive me about this computer is that it's not a me-too. Unlike Android, you can't pigeonhole it as just another iPhone knock off. It's fundamentally different user interface is stunning and unique.
Here's the venerable (yeah) Walt Mossberg's review:
"But the tablet I'm using is very different—historic, actually. It's the first personal computer made by Microsoft, a company determined for decades to make only the software driving others' computers." (from Wall Street Journal)
In addition to the computer and the new version of Windows, these computers have a unique keyboard built into soft screen protector. Very cool! Secondly, the tablets have a built in 'kick-stand' for standing it upright. Cool again! Well done Microsoft!
