Heres the specs:
1.83 ghz Core 2 Duo processor
2 gb of memory
80 gb hard drive
Built in Webcam
Dell XPS M1210: $2032
I tried to make the computers as similar as possible. As you can see the Mac is actually CHEAPER than the dell.
There are a couple differences though. The Dell comes with a TV tuner so subtract 150 dollars from that. Also it comes with a mobile broadband antenna so you can probably subtract another 150 dollars. Also I'm not entirely sure that the Macbook has Wireless N. I know the Pros have it but I'm not 100% sure on teh plain old macbooks. So you can subtract 50 more dollars if you want to. Also the macbook has a 13 inch screen while the dell has a 12 inch. So you can probably add 100 back to the Dell. So I guess the dell comes out to about 1750.
Surprisingly the Dell is the more expensive computer. This kind of goes against the argument where most people say OMG Macs are so EXPENSIVE!@ PeeCees ruLe. I'll admit that Macs are pretty expensive. The reason is because they're all good computers. The slowest processor in the Macbooks is the 1.83 ghz Core Duo. The fastest one in the Dells that werent the XPS models was only 1.73. You get what you pay for with computers.
