I definitely wouldn’t get a Dell if you are going to go the PC route (as the majority of my job is replacing their complete crappiness with something slightly less crappy like Lenovo). The only difference b/w Mac and PC is the users and the way the OS looks, both OS suck because of their ludicrous competition, secrecy, closed-source and total focus on looks over functionality. The two party system thing doesn’t work in any realm.
Mac’s are more responsive, load less items on startup, have Apache pre-installed (sweet), better comes-with software and yes, seem to have the design field captivated. They also make basic system administration a f’ing nightmare with CTRL + APPLE + F9 + X + T + HOME + “Spin around three times” to reset the pram and nvram so your OS doesn’t continuously crash. Or you can go talk to a Mac “Genius”, who is not going to be pretentious at all, and will definitely be a genius. In my experience, Macs tend to crash out of the blue (spinning rainbow of death), I used my then-top-of-the-line G4 Powerbook to do mobile recordings with a gang of ridiculously expensive equipment and software, and I can’t tell you how many times I wanted to stomp on it for 10-36 minutes when it crashed out of nowhere, with no error message.
PCs are well supported, mostly stable (depending on Windows version you run), easy to administer and fix yourself, and most of all CHEAP. Not as in “cheap, piece of crap”, but closer to the actual cost of the parts and software. You are not paying for the brand (at least not as much as Mac). PCs break a lot, they don’t blue screen that much (no more than Mac), there are a lot of crappy vendors (such as Dell, Compaq) out there, Vista kind of sucks, plus Macs and their OS are much more fun to look at, which being a design person, you probably are interested in. It all makes sense to me now…
LINUX, FTW!!!
No matter which way you go, you will be happy, pissed and excited at some point. What you should care about is processor speed/# of cores, installed RAM, firewire, DVD/HD burner, DISK SPACE (though that can be fixed later), Motherboard quality, and how helpful support is.
