Hello everyone I am new to the forum and relatively new to macs. I am comparing both Dell's 6000 15" widescreen laptop to Apple's Powerbook Laptop. The dell would come with a 1.6GHZ pentium M processor with 512MB of memory and a 128mb ATI graphics card for under a $1000. The powerbook after my educational discount and a $100 off that an apple sales rep said they would give me a 15" powerbook at 1.5GHZ, 64mb nvidia graphics card, and 512Mb of ram would cost over $1700. now to me the dell seems like it will be more powerfull for less money. Can you please explain to me the difference in measuring proccessor speed between the dell and the mac, and what other differences I should consider. THanks in advance.
