Well, that and all the other reviews, screengrabs and videos that you haven't bothered to look at, of course.
Are they all as fact- and analysis-free as this one you recommended?

"Look at me! I've got a Windows 7 preview! It's cool!"
No, let's be serious and look at the facts.
1. "The OS installed in around 35 minutes, with only two or three restarts"
You only do it once, most users don't
ever do it. No big deal.
2. "Windows 7 takes up less disk space than Vista."
At around £75 for 1TB at current prices (let alone what they'll be when it launches), the difference probably accounts for about 30p of savings. Gosh!
3. "a cool, Aero-graphics-based OS"
Fact-free puff.
4. "great connectivity to devices (cameras, printers, phones)"
Vista doesn't seem to have a problem connecting to my cameras, printers or phones.
5. "I'm betting Windows 7, streamlined as it is, will be a no-brainer for business, even given that its hardware requirements are more like Vista than like XP."
I'm betting that businesses still won't have a compelling reason to upgrade until MS forces them to with restrictive licensing agreements.
6. "judging from the smaller footprint of the OS -- that Microsoft has done a lot of ground-up rewrites of the guts of the code".
And how does this translate into user benefits?
7. "the upshot is that I'm convinced, even at this early date, that Windows 7 is gonna be a winner. The only question left is, when will Microsoft launch the thing."
I'm glad you're convinced. I've yet to hear one compelling reason at least in this piece why anyone should upgrade from either XP or Vista.
