MS has a horrifying record of failing with tablets, portables, ecosystems, and mobile OSes, even when they put the full force of their cash reserves and marketing power to bear.
Microsoft Kin, DOA
Microsoft Zune, dead
Microsoft "Plays for Sure", dead
Microsoft "Zune Music Pass", dead
Every Microsoft tablet ever, DOA
Microsoft Windows Mobile, ALIVE! And all 62 people who have it, love it.
I'd be afraid to be an early adopter of yet another failed MS platform.
1) Type cover (with trackpad)
2) Built-in kickstand
3) Ability to upload documents
4) Microsoft office
5) USB
Those are compelling reasons,
if they work well. MS is keeping this thing under such tight wraps that there are no reviews. Press events have been hands-off. Anyone pre-ordering this is essentially buying blind and hoping for the best. For all you know, the Type Cover is unreliable, the kickstand breaks easily, uploading documents is tedious, Office is unintuitive or buggy, and the USB port is flawed.
Sure, all of those things could also work flawlessly and with incredible sophistication, but this is essentially my point...
we don't know.
Why the hell is MS hiding this thing? Get some review samples out to the press for crying out loud. Anyone preordering this thing is doing a blind buy on faith that a company with a track record of failure will get it right this time.
In the movie industry, it is not a coincidence that review screeners often don't go out ahead of time for movies that suck. It's because they want to sell as many tickets as they can before the bad reviews sink in. I can't help but think MS wants all your preorders before the reviews hit.
Now if all goes well, it's a great success, has great reviews, developers make apps, etc., I could see myself getting one. But it's going to take a year or two to build my trust.
