If Microsoft delivers on the Phone <-> Tablet <-> Desktop connection, with:

  - A decent ecosystem
  - Free from totalitarian-regime control
  - Access and compatibility with a wide range of current hardware devices:
    - USB mice/trackball
    - USB external drives
    - Monitors
    - Keyboards
    - Printers
    - Speakers
    - HID devices
    - Bluetooth without requiring a proprietary chip
    - Non-proprietary peripherals in general
    - USB memory sticks
    - And generally anything that can connect to the device
    - Without requiring the King to bless what you are doing
  - Freedom from the 30% death-tax on mobile devices
  - Freedom to write any app you care to for mobile and tablet without 
    the need for Royal authorization
  - No requirement to buy super-custom-secret chips to do hardware
  - No onerous requirements for expensive approval process on hardware
  - Easy and publisher-controlled app updates
  - Decent device pricing
  - Wide availability
  - Interoperability with existing systems
  - Application compatibility (Desktop <-> Tablet)
  - Sensible app deployment requirements without having to package megabytes of
    crap you don't need for a phone just because you also want to offer the 
    app on a tablet that has greater resolution.
  - And a few more things I can't think of right now

I, for one, will cast my vote and support their efforts both as a developer and consumer. If anything because I have a very strong feeling that Apple needs serious competition to remain in check. They have taken a far too totalitarian approach to their offerings and it is not getting any better.

Of course, I'll continue to support Apple as well. Just hope they see the light and consider taking off their sometimes-not-so-benevolent-dictator hat.
