We're preparing to roll-out Windows-7 on an organizational level this year. Finally, 7 is beginning to approach the stability and reliability of XP.

Microsoft has a long history of releasing OSs before they are debugged, and it costs money to have employees sitting around doing nothing because their system crashed. Vista never really got to the "stable" level before MS turned its attention to 7. Like ME a decade ago, Vista was a stepping stone that ended up being a stumbling block in the path.

Instead of "feeling the need" to upgrade just because Microsoft had something new, we chose to wait until the new offering reached a solid level of acceptance by the general user community. So we "refrained" from upgrading immediately, instead choosing to remain on the stable XP platform until the next generation was ready. Vista never made it. 7 did, and we're moving forward now - AFTER Microsoft has done the debugging.
