I'm holding on to my ancient 400mhz Tibook because Apple basically replaced all of its components -- logic board, middle case, trackpad, everythiing but the screen, which is great, before warranty ran out last August. I love the machine. I maxed to 1gig of ram and a 5400rpm 40gig travelstar hd. I upgraded to Panther and the only thing that is bugging me at moment is that I am getting the spinning beachball way too much. I don't game. I use Word and surf the internet. That's it! Is my machine just too slow? I'm only using about 9gigs of the hard drive space -- so why do I have this beach ball delay on websites and even when I use Word? Very frustrating. Any clues or ideas appreciated. I could upgrade CPU to 550 through Daystar (chickened out at last minute as I don't like shipping my pristine machine across the country). Or should I get a faster 7200 rpm HD maybe?
