Enough with the "Professional" and "Toy" approach, the only differnce between a A500 and a A2000 is the expansion slots. Take a stock A500 and a stock A2000, say you wanted to add a hdd to each, for the A500, attach an A590, for the A2000 install a A2091 card, same outcome, just looks different. Same can be said for RAM, for the A500, add some RAM to the A590, for the 2000, add some RAM to the A2091, once again the same outcome, in the end, yes you can do more to an A2000, but if your spending that much money, buy yourself a A1200 with an 040 accelerator card and you will beat any expanded A2000 hands down. So much more I can say, but I am busy working, so get over it. My appologies if I sounded rude.
