Over the past few months I have plannning to purchace a new computer. I have had limited exposure to Macs in the past, and my current system runs both Windows XP and Linux. I have been very happy with Linux bar the lack of complete stable applications. That is why I have kept Windows XP on my machine. I decided to have a crack at working with a Mac, however I'm unsure what system I should get. If I do purchase a Mac, I want to do the following using it: Play Music (Ogg Vorbis Format). Play Videos/Movies (DVD & DivX etc). General Internet Use. Office Productivity. Watch TV (TV Tuner Card) I will continue to use my current system for (not on new Mac): Graphics, Sound & Video Editing. Games. As I mentioned before, I don't know what system I should get. I have noticed that Mac prices are far higher (double at least) compared with parts I can buy to build a new x86 based computer, so I am wary about how much I want to spend. Another problem I have is that Macs value systems seeem to come standard with 256MB or RAM, and the upgrade to 512 is just so expensive. I would be happy with 256MB but I have heard that Mac OS X uses alot of memory and I'm the type who doesn't like any lag at all. What Mac system should I be looking at?
