I am a double-switcher.
I was a Windows software developer who switched to Linux and then to Apple.
I liked my Powerbook had two of them. They were definitely king before Vista and Windows 7. My kids never caught a virus or any malware when using the Apples.
However, when my Powerbook died I couldn’t justify the $2000 replacement cost. So I bought a $550 lenovo laptop running Vista.
To my surprise I was happy to be back on Windows. (It was an unexpected feeling of relief.) When on Apple it was always harder to find software - not impossible, just harder. Also, printer utilities and such provided by hardware vendors are better as well.
Occasionally, I do miss the OSX/BSD shell but not often. And, I do miss Spotlight - probably miss spotlight the most. But third party indexers do help bridge the gap.
My lenovo has lasted 1 year of pretty rough usage. If it lasts two years then it will definitely be worth it. (Because the Apple stuff lasts forever)
Have you tried Powershell?
