Although they have made some much needed improvements to the Surface Pro (including a more rigid backlit keyboard - hallelujah!), the core problem remains - this is still the wrong form factor for their target market, the business user. Screen too small, hard to use on your lap and not enough ports.
If the Surface Pro 2 existed in a vacuum I would say this could be a big winner, but it does not. While SP2 has upped its game so has the competition. Surface 2 looks great except that it will be competing against Bay Trail devices which can run full Windows 8.1. Also, not including a pen with Surface 2 for students is a major major fail. That's like scoring the tying touchdown with a second to play and missing the extra point.
So needed improvements to both but big flies in the ointment if actually selling tablets is MS's goal.
We'll see. The Surface name is already so damaged it may be hard to recover. Branding goodwill means a lot as Apple just sold 9 million units of a crap upgrade just because it was an iPhone.
