Macs are what I'd call "all show and no go". You get a nice looking machine that is smooth for daily tasks. However, if you try to actually do something intense with it its limitations become very clear very quickly. You also spend a lot for what you get, which is a big part of why they are like that. The only redeeming part of Mac is the build quality, and the fact that the OS is Unix-like (though for a Unix-like OS you can always boot Linux or BSD on a PC).
Even that isn't really the case anymore. I have seen several Windows machines that have comparable or even better build quality than the Macbooks, and there's some bad things (e.g. keyboards, Flexgate) that could happen on a Macbook.
