I just took the plunge and bought myself a PowerBook. Aside from some abysmally stupid design decisions (no being able to natively play oggs in iTunes, or natively watch my compressed movies in QuickTime. Not having (finding easily?) the choice to sort folders such that everything is in alphabetical order, except that folders come first.), I'm quite content. I've figured most everything out, and my "switching jitters" are almost over. It really is a fantastic platform, and I can't imagine ever regretting the switch. Except... I've had the computer crash twice in the 4 days I've owned it. Basically, it gets to a state where nothing really works right anymore and I feel the need to reboot (Although I fully admit that this is just perhaps a windows reaction. If someone knows a better way to return the computer to a state where everything just works, let me know). Both times it's crashed, it's been while trying to shut the computer down. I just get a nice blue screen with a spinning cursor (that looks an awful lot like the Macromedia icon). This goes on as long as I'm willing to wait, until I force the laptop to turn off by holding down the power button. On reboot, everything's fine and normal, and the computer runs normally again. Now, a little background: I've installed a fair number of, well, hacker programs. For example, KisMAC, X11, Gimp, OggDrop, MPlayer OSX 2, Adium, Skype, NeoOffice, Firefox, and Thunderbird. So I completely accept that something I've installed is causing some issues. But I cannot for the life of me figure out which could be causing all these problems. Another thing that's really driving me batty is that the Disk Utility refuses to erase my CD-RW. It just gives me an error. Which is absolutely bonkers, because I can't imagine what could stop an Apple from erasing a CD-RW, when a Windows machine has no problem. When I get Tiger from my student ADC membership, should I just erase everything and restart? (When Apple installs an OS, do they play the same nasty tricks that PC manufactures do? That is to say, not giving the CDs with all the original software? I discovered QuickBooks NUE, and I really, really think it's fantastic. It fills a need I never knew I had and I'm scared that if I format/reinstall that I will lose this program.) In fact, since I need to install Gentoo Linux on the machine, and I noticed that the entire HD is already partitioned, wouldn't I need to repartition and reformat anyway? Thanks for any help/suggestions you might have.
