i hate how everyone bitches that they are so expensive. macworld magazine did a test where they took a stock mac pro and customized a dell as close as they could to match the specs of the mac pro. now granted, these are extremely high end computers costing $3+G's, but the dell ended up costing like 300-500 dollars more. Now a comparison like this is always going to be flawed, not to mention it is done by a mac magazine, but for the quality of parts you are getting, you can't beat a mac.
there was also a lot of bitching about tech support with many companies above. I've only dealt with dell tech support before and it was ok. they helped me reformat my comp, but it took many phone calls. for those of you mac owners who live within a reasonable distance of a mac store, you can just bring your machine there and get you tech support done. it is very nice to deal with an actual person when getting tech support, not to mention a person who speaks english as their first language.
another thing, i always had to buy virus software, spyware software, ect for my dell. plus the cost of my time installing and updating the software. plus my time reformatting my dell when i had a virus.
with my macbook pro, i don't worry about a thing. someone above said that the time will come and they are correct. but it's going to be awhile. and by that time, there will be some kind of fix. apple is pretty quick to patch up their software.
and applecare is a must. no questions asked.
