i want to switch to mac, because i think mac is beautiful, the design of the machine is great. And i heard that it has less problem compared to Windows. With windows, you have to have antivirus, with antivirus installed you will still have some spyware running that could make your machine slow. In Windows, for the first time you set up your machine, it's fast, but when using it for times, it'll get slower and slower. This probably caused by the messed up Windows' registry. Like After G said, when you have problem with your windows, just reformat and reinstall, yeah thats right 🙂
I'm using computer for general office, presentation, browse through net, and sometimes game. Mostly i play game with console though.
And one more reason why i want to switch to Mac, i like UNIX more than Windows' Command line 🙂
