Relax! No-one is putting words in your mouth... this is a discussion board. The statement to which you're reacting negatively was a rhetorical flourish.... :)

My comment was in reply to your statement that you can virtualize Linux and that makes the MBP an equivalent platform, and I posted because I've gone through these issues and it wasn't fun. The MBP really isn't good for Linux because of the battery issue and then a host of other small problems (sleep, etc.) that make installing dual-boot troublesome:

I'm glad that you can do your web development work on Mac. They are really nice machines. But if this guy needs Ubuntu it is probably because he needs software that runs reliably on it. Knowing that Photoshop will run on the MBP isn't a great impetus to switch when you need to compile various non-default libraries, setup software that isn't packaged with port, or work with almost anything coded in C or C++. This doesn't mean that Mac isn't good at what it does. It just means that if the guy needs Linux, he shouldn't think MacOS is equivalent just because it's based on Unix.
