Sorry to burst your LOL-MS-SUCKS bubble, but Office is still the best Office suite out there, servers with Windows Server OS are still being sold, there are hardly any good alternatives to Exchange or Sharepoint.....
While I don't disagree that Exchange and Sharepoint are good, I would like to see how you're arriving at "no good alternatives" and how Office is the best office suite. What metrics are you using?
And no, OpenOffice or Lotus Notes is nowhere near as useful as MS Office is.
According to who? Entire government agencies are switching to either Open Office or Google Docs. Apparently they feel it is useful.
Windows Vista was a media failure, if you happened to use >SP1 you would have noticed how many of the issues were solved already. Windows 7 is just Vista but less resource intensive, faster and a bit easier to use. The same paradigm is still there.
Yes, Windows 7 is Vista but less resource intensive, etc. That's a pretty huge distinction though, since Vista is/was an absolute pig.
