In reality, I don't think the difference is large enough to justify putting out the extra $500 for an extra 200mhz of power. Granted, the graphics are a little better and the HDD a little bigger, but for me at least, I can't justify $500 for 200mhz of extra processing power. For someone who is constantly using processor hungry applications it's probably different. For me, I'll take the 2.2ghz and be happy.
