This goes out to Blah Blah: the Apple Mighty Mouse is not a one-button mouse. There are four actual buttons--one on each side and two on the top. Even the Apple Mighty Mouse is better than what will come with a PC!
First off, 2GB RAM is basically standard at this time.
Now, to answer your real question, I am currently stuck using a Windows-based PC. There are two in my house right now--one with Windows XP and one with Vista. The one with Vista is probably about seven-years-old and very slow (has been for five years now--slow, that is) and the newer one, with Windows Vista, isn't even one-year-old and it's already slowing down.
My last year in high school, from 2007-08, I was enrolled in two classes in which I used eMacs (sold between 2002 and 2005). Not only were the eMacs faster than the seven-year-old Windows-based PC I have, but they were also much faster than the new computer I have.
Here's some facts about Macs and the Mac OS X:
The Mac OS X is built on a UNIX foundation which ensures security and resists crashes. This means that Macs don't get viruses and that they very rarely crash. The truly ignorant PC-only users will try and say that Mac OS X Leopard isn't even as stable as Windows Vista, but Mac OS X Leopard much more stable. For one, there are somewhere over 118,000 viruses that Windows may become infected with. However, there are zero viruses that Mac OS X may become infected with (not just Leopard, but Tiger and Panther as well).
Then, of course, PC-only users will usually say that Macs can't do as much and that there is much more software that's only compatible with Windows and not Mac OS X. That's completely untrue. For once, Macs can run both Windows XP and Windows Vista through Boot Camp, which comes on all Macs. Because of this, Macs can run the Windows version of Microsoft Office, MOST games (as long as the graphics card in the Mac meets the requirements--just about every other require is met by a Mac), etc.
Then, for iMacs and Mac Minis, there's the size. The Mac Mini is the world's smallest desktop (I've honestly never seen one smaller anyway). At probably about one-inch-tall and only about six-inches diagonally, the Mac Mini is so small that it's smaller than any laptop I've ever seen. Now, the Mac Mini starts off at $600. The iMac, on the other hand, starts off at $1,200. The iMac includes nothing but what appears to be a monitor. Instead of using a tower to store all of its components, the iMac stores everything directly behind the monitor. What's more is that the iMac can have up to a 1TB (1000GB) hard drive. Big enough? Most people won't need that much space on their hard drive. Then, you can have up to 4GB RAM.
Now, many PC-only users will also say that Macs just aren't nearly as fast as Windows-based PCs. Of course, I have used eMacs that were faster than brand new PCs. I've also read (some article online--found it through Google by searching, "Mac vs. PC") that Macs ran Windows Vista more efficiently than PCs did. Sad, isn't it?
Trust me--a Mac with just 1GB RAM will probably outperform any Windows-based PC with 2GB RAM. How is this? It's simple--Apple takes time when developing products. When Microsoft develops products (mainly the Windows OS), they basically take some ideas from Apple and make them about 10 times worse so that the computers that use Windows will be able to be sold for very cheap.
Honestly, if it weren't for the price of Macs, they'd outsell every PC-making company in the business and in a heartbeat!
One last thing before I finish: I would only recommend a PC to those who want to play a lot of computer games. For anything else, including business (typing, spreadsheets, PowerPoint-style work, etc), but especially graphic design, web design, video production and music production, I could only recommend a Mac.
Now, here's a list of all the Mac models (find out info through the links in the source area): Laptops--MacBook, MacBook Air, MacBook Pro; Desktops--Mac Mini, iMac, Mac Pro
