I customised mine from Dell like three years ago so it's pretty out of date. At the time it was good but yeah. And people that bash Dell for no apparent reason should kill themself, they're fine if you reinstall the operating system.
Anyway, all I have to say is don't get a Mac. If you like the operating system either kill yourself or install it on another computer other than an iMac or one of those shit all in one things, or just install Linux which owns the fuck out of Mac's and runs on basically the same kernel. Mac stole it etc.
