Mac Attack

Uhh...apple.com says $1299 for generic macbook...i sure hope thats not your definition of cheap

wow.... where do you live where macs are considered *cheap*?

Over here (western europe, to be precise: the netherlands), macs are anything but cheap. Last time I checked a macbook was about 400 euros more expensive than a 'normal' laptop with comparable specs.
And for OS-X, it takes some getting used to. Like every OS.

But yes, #! can be installed on a mac.

I run a different Ubuntu-based distro on a Macbook Pro and it's pretty much all great, out of the box.

Have a look at the Mac Ubuntu guides here https://help.ubuntu.com/community/Intel_iMac as a lot of the material will be relevant. In particular you're likely to want to install a program called Pommed to make some Mac features work (backlit keyboard, certain function keys, etc.).

But mostly you should just find it works really well. However, as others have said, you can get similar spec hardware for less money. If you like Apple design (and why wouldn't you?) then the premium you pay might be worth it. But a large part of the premium you pay for a Mac is for the guarantee that Mac OS (which is just another Unix) works flawlessly with the hardware. It's a hard- and software bundle and has a lot to recommend it if you like OS X.

Mac computer are same than other pc now, they haven't any difference, so you can istall crunchbang in a mac
But why a mac? there is pc whit same config less expensive than mac, dell is a good exemple

I love how she says "it only has 2 gigs of ram" and then she cant say anything cause she doesn't know what the hell she's talking about... 2 gigs is more than enough to edit video you stuck up bi*ch. If you knew soooo much then why the hell do you need a sales accosiate??
2 gigs will run any operating, plus, ram has little dealings with video editing. what you need to look at is the damn processor.

[starts going into a rant about people who think they know computers but then when you mention linux they say "whats that"]

Only 2GB? I don't think Id accept that either, if only considering even cheap laptops have 4GB.

I have a mac with #! and Mac OS X side by side

1. Mac is (still) not a regular PC - there is no Bios, so if you want a dualboot you need to install an additional software (follow macintel wiki). Most important is to set a min fan speed upto 3000 so your mac will not cook (mac gets hot with linux - don't ask why )
2. It is not recommended to delete Mac OS X.
3.Yes, Macbooks are sometimes cheap  - few years ago, my white mac was the cheapest 13' notebook I could get (with a student discount)
4.With 3GB of ram you can run almost any OS in virtualbox within mac os x - with no pain. That is how I run Windows XP and sometimes some other linux distros - to be honest it is the easiest way, and sometimes the best (and safest for mac) way
