You wanted people to be more critical of things and he is. He does not have the same experience as you do or as I have with Dell and that was his point. Some people stick with Dell, some with Apple, some with Lenovo, etc. Why? Because of previous experience they have had with that brand and other brands.I spent equally as much time on the phone with Apple over issues. Why do you assume they are immune? Lot's of myths out there.
In fact the laptop that lasted me the longest with zero problems was a Compaq...and they are supposed to be junk.
Personally I'd get a Dell if I wanted a Windows or Linux desktop machine because they do the job and are reasonably priced. I hate the fact that the prices on their website are completely off compared to the real price, it's very misleading to customers. Other manufacturers/OEM's do a better job at that (like Apple). Regarding monitors I'd go for Dell because they are far better and cheaper than the ones from Apple (outdated and glossy is not something I want) but Samsung seems to be a very good one as well (and cheaper but you'll loose some features Dell has like native DisplayPort).
When looking at UNIX machines than you have Sun (now Oracle), IBM and Apple as the big brand names. When looking at UNIX laptops you end up with Apple, there are no other competitors I know off (there may be others though). When looking at price Sun can sometimes match the low price tag from Apple machines so when UNIX and low price are what you want it's Apple you need to look for.
Btw, if you look at Lenovo Thinkpads and configured (!) Dell machines the prices match Apple's or go even beyond it. Same goes for Sun. But Acer notebooks or noname notebooks can be a lot cheaper but it will come at a price regarding (build) quality. It really depends on the components and brand you choose. This makes comparing prices and specs rather silly.
Moral of this story: it depends on what you want and what values the most to you. You need to decide on what you want to get but others can help you with that choice. In the end you're buying it and using it, not someone else! As far as the MBP goes, it's a great laptop with a glossy screen that you either love or hate.
