Because my current employer has a select licensing agreement with Microsoft, the final version of Windows 7 became available to us a few weeks ago. Out of morbid curiosity, we downloaded and installed it on a couple of systems that we had been running Windows Vista on. It almost pains me to say this, but Windows 7 is a very nice operating system. It is everything that Vista should have been.
It is faster. After a short problem with a wireless driver, it is much more stable. (Did I mention that it is faster?) I’m also quite taken with the new task bar.
I’ll post more as I can, but my impression after about two weeks of use is that Windows 7 is the new Windows XP.
