So I have been running MacOSX 10.4 (aka Tiger) for about a week now. It seems pretty nice. It even seems to be faster on my computer than 10.3. Dashboard is pretty cool. My dual 450Mhz is pretty long in the tooth. It will be five years old in August. I never thought that a computer would last me this long. When I get a job I think I will look at a 20″ iMac.
