Hi! I am going to get myself a macbook in some two weeks. I chose Mac, mostly becouse of the operating system, which I find very easy to use and friendly. But I have a few (lame?) questions.. 1) is Mac OS X going to work for a long time? Windows is a very cool OS for the first month, and than it becomes slower and slower and reaches the nadir after ~6 months I played with Mac OS X in the Apple store for a while - but is it going to work after 6, 12, 18 months? Or will I have to re-install it every, let's say, year? 2) what happens after programs are installed and re-installed and un-installed? In windows every re-, un- or installation is risky - becouse after each the system is more and more clumsy. Does the same happen on Mac OS X. Do I have to be carefull with how much things I install or I can install and re-install what I want and when I want, and the system will be OK? 3) if I will add additional fonts to the system (I own Font Folio), will the system be much more clumsy and slow? If I will run Mac OS X + Font Folio on 512MB MacBook - will it work (i'm going to upgrade RAM, but not in September ). 4) Does something like a command line exist in Mac? I believe so. If it does - where can I find any tutorial or help, how to use it? I like the text command line, I used it in Linux - it's great. Thank You in advice!
