The history of advice about Vista:
2006-7: It’s pretty buggy, wait till they get the kinks out
2007: It’s such a resource hog, wait until you buy your next (bigger, faster) machine and get it free rather than spend the cash for new RAM, etc.
2008: The economy is so bad, WinXP will hold you over and maybe they’ll get more bugs out by the time you can afford it.
2009: Windows 7 is going to be out shortly, why not wait and skip VISTA entirely.
2009 (second half) Whoa! Windows 7 looks pretty nice! Look how fast it starts!
Information Technology Intelligence Corp. of Boston (partnering with Sunbelt Software) found that half of the 1,200 companies they surveyed expect to move to Windows 7 in the first year it is available. Eleven percent of those surveyed said they expect to install it after the first service pack.
Windows XP, which has been around for eight years, will be supported until 2014.
