I freely admit that I am a Mac user. OS-X just works better for me, and my workflow. But I will grant that Windows 7 is pretty good, and usable.
Of course, since I work in the corporate world, I am forced to use Windows (well, in the past I have been a rebel and was a Mac in a PC world, but I stopped beating my head against that wall). For the most part, Windows is fine. I even like Office 2010 and the ribbon interface that was introduced in Office 2007.
But, for some strange reason, I have glitches in my email. We use Exchange and Outlook for email and calendaring, and it seems about once a week the OST file (where outlook keeps local data) borks. This leads to not being able to send or receive emails until I repair the OST. Which requires me to quit any applications that access the Outlook API and the OST file. Which means that I really have to reboot to scan and fix the errors. And since I have a PGP Whole Disk Encryption, it takes about 30 minutes for the services that hit the disk to be done after a reboot.
Sigh, so go through all this, and run the tool (3 x until I no longer get errors in the scan), and then I can get back to work.
Lost hour of productivity, because Outlook decides to freak out.
Tobe fair, I have had some data issues on my mac, and keep much larger stores of email locally but they are fewer, and recovery doesn’t require running a program that looks like Windows NT3.51 vintage UI (the scanpst.exe program) to recover.
