Hi, need your opinion please. I have a ibook - 12", g4 800mhz, 384 ram 30 gig hd. Had it about a year and its going okay but is really slowing down now and has around 800 megs of space left. I'm looking at getting a powerbook buts its around 250 more that the ibook once i have done my desired upgrades to it so i'm thinking i might just get a ibook until the new intel powerbooks come out some time next year or whenever it may be. Just wondering though, do you think it is worth me upgrading? I am already running tiger so the upgrades i will be getting would be 500 Mhz, 128 ram and about 50 gigs of space. Would i notice a increase in speed? I currently have a dell desktop but want to ditch that and use this as my main machine. Do you think it will do the job?
