Hello, I'm from Jamaica, where it is 99.999% Windows and I'm also a Windows user. The other 00.001% is the News Paper company that uses Macs for Page layout. I'm taking a trip abroad Summer 2004. I would like to know if it will be possible then to get a Second Hand PowerMac G4, 800Mhz for U$300. I really want to try OS X, its so freaking HOT! I also would like to know, will future versions of OS X, possibly 10.4, 10.5 and 10.6 be able to run on that Mac when they are released in the future? Because if OS 10.3 can be running on a 300 Mhz White & Blue G3 without any hitches, why would it be impossible for future versions to run on a 800 Mhz? In terms of Memory I will add more to improve performance. Does anybody know where I can get all the older versions of OS X at a very cheap price, versions 10.0, 10.1, 10.2. I want to start from beginning up to the very latest, just to see how it all began.
