I'm a PC user and will always be a PC user.
Calibrated display? Get a real calibration tool. Mac is no where near the right one if you take into account the ambient light in your workspace.
Specs? With 80k (for example) I can get a much more powerful Laptop and a much more powerful desktop packed with 12gigs of RAM and the latest i7 2600k and ATI or Nvidia *** @ 1gb gddr 5 with a superior AOC lcd monitor. I can play crysis 2, while running a quick encode on a short video I took on my last assignment, switching to my lightroom to find out that it has already finished exported, burned the files to DVD and switch back to Crysis 2 game and not feel a slightest lag. Where's mac at?
Viruses? <-- only noob and careless PC users get infected. Plenty of viruses? It's a consequence resulting from the popularity of the windows OS. Why make viruses for an OS used by the lesser few?
Experience
<-- very subjective. I meet people who hate Mac too and this is probably where it will mater most for people. some people love the plug n play feel of Mac. Me, I love tinkering around.
Just don't talk about specs because there's just no way a mac can be better than a PC in terms of specs. That's why the best and most graphics, cpu and ram intensive games can only be found in PC.
For the best overall experience in computing, get a PC. The PC can deliver better hi performance for the same amount of money invested.
about your thread title, is the comparison - mac (book) vs any laptop or a pc within the price range of the mac book?
