We all are excited about the Windows 8 Consumer Preview. Microsoft gave us a really fast and stable OS preview at the end of February.

Only a few minutes ago Microsoft announced via twitter that the next version, a Release Preview, will be available in early June. They announced it while they are on Japan Dev Days. Earlier this week Microsoft announced also that the Consumer Preview is now already used twice as much as the Windows 7 beta at the same point in time.
Windows 8 consumer preview usage more than twice Windows 7 beta at the same point in time. Millions of people using everyday.#thankyou

Personally I do not wonder about this. W8CP is a preview you can use as a daily driver already, and many of us are doing so. And it seems that there are a lot of people are beginning to like the Metro part of Windows 8.
