Frankly, 1 gig is probably not enough. What will happen is that your computer will start using "virtual memory" -- swapping out pieces of programs in memory to your hard drive. This is very slow, as the hard drive is about a thousand times slower than RAM. But the good news is that you will go to Memory upgrades, flash media, and usb storage at Crucial.com and buy four gigs of RAM for just over $100. Don't buy it from Apple -- they want $300 for the same memory. It's a bit of a pain to do the upgrade, as there are three tiny screws holding in a little metal bracket that you have to remove. If it scares you, find a friend, relative or neighbor to do it for you. It's a ten-minute job if you have the right tools (basically, one of those little eyeglass screwdrivers). With four gigs of RAM, you will be able to run Mac OSX and Windows simultaneously, with several programs running happily in each OS.
