Wow, here I go again - another post! This thread has got me thinking about a lot.
Anyhow, I just want to comment about people who complain about their Macs on this forum not doing what they want then whining about it with no intention to learn, but just to whine and make their experience (or lack thereof) the benchmark for all Macs. I've found that if ANY computer - Mac or Windows - is frequently doing things like crash, hang up, etc. no matter what you try, then you have some kind of serious hardware/software (or personal?) issue. Especially with a Mac; problems like these are much more common on PCs (I base this upon extensive personal experience AND other peoples' stories).
In this case, contact Apple support and make sure it's not a problem with YOU before crying the blues here. Maybe you should have spent a few extra dollars (or pounds) on RAM instead of cheaping out, or maybe you should close some apps if things are slowing down, etc.
And concerning the "you" part, don't just buy a Mac because some Mac ad convinced you that computer use would be trouble-free if you get one. DO SOME RESEARCH FIRST!!! Spend a few weeks, even months, on forums like this. Buy magazines. Do whatever it takes to be fully informed about what it is you wish to do with a computer, what applications (programs) you'll need, and even which system - Mac or Windows - will serve your needs the best.
If you really want your Mac to perform a certain task/function but only know of a Windows program to do it, RESEARCH to find if there's a Mac equivalent - there almost always is. Don't just buy the Mac then b*tch about why it isn't doing what you wanted because you were too lazy and impulsive to take the time to do your homework. The two months I spent on this forum and doing other research before I even decided to buy a Mac saved me some headaches by the time I got it - I knew what and what not to expect, and realized that any decision I had made to switch was MY responsibility and not the fault of Apple or anyone else.
I find most Mac users are very computer-literate, having either worked with Macs for years or having been Windows users for years before getting annoyed and looking for an alternative like a Mac. It's no wonder, then, that most switchers HAVE been satisfied and reporting almost trouble-free experiences. Even when they have the odd problem with their Mac, they have extensive experience with computers to know how to find out how to solve it. And if they lack experience, the satisfied Mac user seems to have at least taken the time to ensure that a Mac would do what they wanted a computer to do for them before they bought one.
