There are some nice features in Windows 7, but:
1. For most processes (spreadsheets, word processing, Listening to mp3's, databases) my classic Amiga is just as fast if not faster than a decked out (16gb ram, i5, Fast SSD) windows box.
2. My Amiga wins hands down for stability. The apps we use at work will crash windows 7 or require rebuilds of data, and frequent spyware removal. My Amiga just runs for weeks at a time answering the phone, listening to mp3's, home finance, and other items without a single issue. To be fair, the PC is handling much larger and complicated databases than the Amiga, but for 20+ years of technology advancement the net gain in speed, productivity, and stability is dismal.
Using win 7 to write this though:)...
