So fast and it never gets hot! I have no doubt Apple made a smart move switching to their own silicon.

This got me through years of schoolwork. It's long in the tooth but is still a very portable machine to keep around the house. Easy to service too, which can't be said for the newer macbooks. I replaced the battery and trackpad in half an hour. The screen is antiquated by today's standards but the main issue is the lack of ram. Mac OS requires 4 GB just to install and all the bloated modern Web sites just love eating up memory. I had Monterey on here but it was slow so I said to hell with it and installed Catalina again. It works fine although the battery is very worn out and I can't be bothered to replace it again.

I use this for running Windows games. It's a beautiful computer but I can't justify upgrading it anymore. I still use the Apple Cinema Display and it's a sweet monitor to use every day. The brightness controls are simple and responsive and the viewing angles are phenomenal. I like the extra vertical resolution especially on Mac OS and the letterboxing on widescreen movies has never bothered me.

I used this as my main portable for a few years. I installed a patched version of Mountain Lion and it works fine with minor graphical issues. The integrated graphics on these were always awful. Playing most 3D games on decent settings is out of the question. Apple says the ram limit on these is 4GB but I've heard of people installing 6GB. These computers are prone to certain cosmetic issues, especially the palmrest plastic cracking but I've managed to keep mine in good shape.

This was my first Mac and I find there's a certain kind of approachability to these white computers. The design is still as stunning as the day it came out. Nothing Apple has put out since Tiger comes close to matching it in speed, reliability or interface design (except maybe Snow Leopard). The hard disk failed years ago so I replaced it with a new old stock one. This machine doesn't get much use but I do break it out every once in a while to play some old games. Wasted a lot of hours playing Max Payne on here :)
