A few years back, I took the plunge and went Mac.  

I don't see myself going back any time soon.

I switched over to Mac in the early '90s and never looked back. For a while it was sort of like being left-handed in a right handed world (lots of applications and even some peripherals were Windows only), but that doesn't seem to be so much of a problem any more. Just recently I picked up a used laptop on eBay that runs Mountain Lion for just over $400 because my pre-Intel G4 running Tiger had begun to stop working on a lot of websites, and all its software was getting pretty ancient. It came loaded with CS6 deluxe, M. Office '11, a glossy screen and NVIDIA card, 250GB of hard drive and is super fast. It's in great shape, too. Incredible deal, even if it was (for me) a lot of money. I just had to bite the bullet.

I used to have a Macbook, but it broke. Now I am poor and I want a new computer. I cannot afford another Mac. Right now I use an old windows Desktop that belongs to my father.

Huh?  I don't speak this language at all!  But I can type 45 words per minute on my grandmother's manual black cast-iron typewriter!  And I remember card readers and carting around batch cards in bundles in shoe-boxes to the campus "computing center."  It seemed such an exercise in futility that I dropped out of the computer geek world.  Only reentered a very little last winter because my job required an on-line course.

Apple should have had the market share that Microsoft enjoys.

I like to tinker, so I prefer Microsoft and Linux.

For laptops, I'm quite fond of Toshibas. They've got some clunkers, but I'd usually pit their best laptop against anything not-NSA-issued.

We've got 2 Toshibas (one I just purchased this year; one from 2009) that are going strong. We've got a daughter who likes "pretty" (silk-screened?) laptops though, and has had a "pretty" Gateway and a Dell for nearly the same cost as the Macbook Air, and neither contraption lasted a year. I strip dead laptops clean for parts, and got the absolute LEAST from those. The insides are so junked up (you half-expect to see DUCT TAPE holding stuff together) it's a wonder they don't self-implode. (I said absolutely NOT on another "pretty" laptop, and she's getting the clunkier Macbook Air... she can put stickers on it afaic).

Desktops, though, I just put a Gateway SX model through its paces, and the bang for the buck was incredible. We can run AutoCAD, Photoshop, and Steam (games) without much of a hitch, and I don't even have a dedicated graphics card [yet]; just out-of-the-box (and de-junkwared). Only bad is Win8, but my husband's gotten used to the "tiles" and it runs Skyrim, so he's good.
