base model macs are fairly competive with Dell/HP/Gateway/E-Machines setups around the same price.
They gouge like *mad* on any upgrades.
the base model, for $1199 has a i5-2400S (2.5 GHz turbo to 3.1 GHz), 4 GB of notebook DDR3-1333 RAM, a 500 GB notebook drive, and a HD6750M w/ 512MB of dedicated RAM (somewhere between a 6450 and 6570 desktop in power), a slimline 8x DVD RW, and their 21.5" 1920x1080 monitor with built-in speakers. Add the wireless keyboard and mouse, and the suite of 4 USB 2.0 ports, Firewire, and gigabit ethernet, and consider that its an all in one, its competitive with the similar Dell all-in-one ($949 w/ the same processor, but bigger touch screen, 1 tb hdd, and 6 GB RAM, but only HD2000 graphics), and the HP all-in-one ($829, but an i3-2120 and only HD3000 graphics). but even there, its $200+ more expensive!
