This does not mean I'll give up my MacBook anytime soon for a Windows machine, and neither will Win7 replace Ubuntu as my OS of choice on the PC, but you have to acknowledge the fact that Microsoft is finally getting the hang of this OS business.
IMHO, Win7 sucks less than Vista - it's snappy, partly because we have much faster computers (at least I do) than when Vista was launched, and is much less of a disruption, even for a XP user. It was inevitable: software designed for XP may have problems with Vista, but programs designed for Vista run well under 7.
Will I drop Ubuntu for it? No way.
Granted, most of those features were added in Vista, but Windows 7 actually runs quite decent on older hardware, something Vista wasn't exactly acclaimed for doing.
Windows 7 also includes lots of features which are handy for portable machines like laptops. Bitlocker anyone? You also have transparent, automatic VPN back into your company's domain, either trough native IPv6 or tunneled connections. In either case IPSec is used to secure communication. In effect, the windows domain model just got network transparent. That's a pretty neat thing in itself.
Again, some things came with Vista, but Windows 7 delivers it all in a much more appealing package.
I'll shut up before I sound like a Microsoft market-droid, but to say Windows 7 adds no features which would make an upgrade worthwhile in the corporate environment is either disingenuous or misinformed.
I think it's worth the upgrade, but 90% of my family doesn't and I'll need to upgrade them with a pirated version once it's released + cracked.
Ok, that is a compelling reason. I stand corrected.
also who knows??, there are new guys (read Android, WebOS, OS-X) who MIGHT be waiting for the opportunity to jump in ... i dont know why but i feel that eventually google will enter the game by getting android from phones to netbook to notebook....!! if the brand like HTC starts making netbook/notebook then i won't be surprise if it comes pre-installed with android !!
Windows 7 will probably get its "foothold" on the consumer market the same way Vista did: when people buy new computers they get Windows 7. I speculate that the vast majority of Windows users are simply running the same O/S that their computer shipped with, whether that is XP, Vista, or even ME (I've been shocked by how many people I know are still running ME (in a vague sense of the word "running")).
Of course that doesn't apply to techies like us, but when you hold mass market share you have mass market demographics.
As far as businesses upgrading their workstations to Windows 7... no way. Windows XP is pretty stable (they've been improving it for like 8 years, it oughta be) and there are few compelling reason for a business to invest in Windows 7. The only way MS will get Windows 7 into the business market will be to force it (via OEMs or by stopping support for XP/Vista).
I think Microsoft's outlook (pun not intended) is pretty gray in the O/S market.
EDIT: changed "no" reasons to "few" as trezor pointed out at least one reason I was unaware of.
