Eh...
You graphics aren't really that great, you did get close to the Mac OS, but it was still preatty off. It was kinda funny, cause I've had the unexpected quit thing a million times. But overall, not all that great.
That being said, Mac and PC's have two different purposes. PC are mainly, anymore, gaming machines. The majority of web servers are Macintosh, the majority of Design computers are macintosh, the majority of big business is done PC, because everyone has a PC, but, no matter what you say, Mac doesn't crash nearly as much as PC, not by a long shot, and I would much rather have it unexpectidly quit than get the blue screen of death. Plus, mac's automatically partition your memory, so when you're program IS screwing up, you're whole computer doesn't freeze till it figures it out, just the one program.
And yes, the load time is a little longer at start up and when you open programs, but jeez dude, stop watching speed line saturated Anime and read a fucking book. Maybe then you're attention span will expand the extra couple seconds it takes.
