I have a stock macbook 1.83. I had an iBook, but it was warped and by the time I got my refund it had been discontinued. Let me just clear this once and for all by saying that if you only have the 512mb stock RAM in your macbook then office 2004 will drive you absolutely insane. If it were any slower it would be going backwords. What an absolue lie for the Mactopia site to say that it 'works great' or whatever. It basically turns a decent computer into an old 386 pc. You shouldn't need 1gb of RAM to use a frigging word processor or email client. Argghh! It seems like everyone who buys these things has already upgraded the ram to 2gb, but some of us (like me) don't have £200 to spare when we have just shelled out £750 on a new laptop!!
