Uh, have you guys looked at Apple prices recently? Where did you see a $5,000 Mac laptop, they have never cost that much. The top of the line MacBook Pro is $2,800. If you max it out with the biggest hard drive and full RAM capacity it's $3,800 and we're talking about a very high end machine. I think you'll find comparable pricing on machines with similar specs from the other PC makers.
If you want to go cheap, a MacBook can be had for $1,100. Max that out with RAM and HD and get the top of the line model and it's $1,775.
Or take the budget route and get a Mac Mini for $600. The top of the line model there maxxed out with RAM and HD comes to $1,350 (you still need a monitor, but those are dirt cheap today).
Apple has become very competitive, a fact which has received a lot of press even in places like PC magazines. That's one reason why they're doing so well today. And the same hardware can run both Windows and MacOS now.
Having said all that, if you have a computer you like then by all means stick with it. It's only a tool. I'm just pointing out a common misconception which is fueled by people talking about $5,000 Macs. For $4,700 you can get their top of the line desktop machine with two 3.0ghz quad-core Xeon processors which is way more than most people will ever need. Naturally you can easily get that price up to $10,000 by adding expensive goodies, but we're not talking about a consumer type machine there...
