I switched over from a Windows computer about 6 months ago, but overall I feel a bit let down with OSX: 1. Finder is an absolute dog in comparison to Windows Explorer. Finder is inconsistent (i.e. folder merge doesn't work all the time, etc.), difficult to use, and seems to be an outdated file manager. My biggest pet peeve with Finder is that it doesn't sort folders on top; doesn't think seem to make sense rather than scanning through 1000 entries to find a folder? Thankfully TotalFinder saved the day for me - but at the cost of another $18.00. 2. Mac apps seem to lag in quality in comparison to Windows equivalents. i.e. finding a decent, stable, compression/decompression tool was a challenge. Closest I could come is BetterZip. Is there a decent RAR utility? Is there a good (free?) download manager for OSX beside JDownloader? Chrome and Flash don't work well in OSX. QuickTime has poor codec support even with Perian, I need to rely on VLC/mPlayer to properly play my video files. 3. OSX Lion networking isn't the greatest. OSX could do with a network browser. 4. Things keep changing between versions of OSX causing incompatibilities. i.e. Hyperspaces worked great on Snow Leopard but stopped with Lion because Apple removed some APIs. This rarely happens in the Windows world. 5. Speaking of API changes - Time Machine stopped working with my old NAS because of a AFP change. I can go on... but I think you guys get the point. OSX has some great features going for it like Time Machine backups, iMovie, FaceTime, Mail.app, but when you peer underneath, OSX seems quite unpolished in comparison to Windows 7. Perhaps my expectations are higher considering a Mac costs 2 - 3x more than a PC... therefore it should be somewhat better no? I wonder how OSX will stack up against Windows 8? Perhaps now that Steve isn't around, maybe Apple can make some meaningful changes to the OS?
