They probably won't ship until the end of this year.
HP & Microsoft announced the Windows Slate tablet back in 2010 & it never made it to market.

In a BYOD world, can enterprise sales provide enough traction for Microsoft to overcome their lack of appeal in the consumer market?
EDIT-
It appears the low end model will be out in October in time for the holiday season, and the Pro version 90 days later.
I don't blame them for trying to vertically integrate, especially after seeing what it has done for Apple. But I think they're too late to the party.
Given how a lot of OEMs are pumping Androids, Microsoft may just have to start hedging its bets.
(On a lighter note maybe we can start a red-ring of death meme).
I think based on the dreck that the OEMs have been delivering for the last 8-10 years, it's not surprising that Microsoft felt it had to jump into the hardware business directly.
Poor PR from MSFT.
Seriously, no release date, no pricing, no real demo (rendered images instead), no software announcements other than Netflix and Office. This type of product announcement might have worked pre-Internet, but nowadays people expect to be able to find out concrete details and pricing once a product is announced.
No demo units shipped to Walt Mossberg or David Pogue, or even a John Dvorak...
This isn't like the Zune however. The Zune was peripheral to Microsoft's core business. This is central to where a large portion of the computing market is headed. If this takes two or three revisions to gain traction, then Microsoft might be too late.
