I'm looking for a better laptop. I've bought "budget" laptops the last 4-5 years and I'm getting sick of their inability to multitask with any sort of consistency. Basically I need something that won't freeze when burning blu-rays, converting 20gb mkv, and transferring them to my synology NAS. I'm not really going to play games on it or anything, but I want some serious boot/programs/transfer speeds on it. I'm NOT opposed to buying used either, so maybe a better laptop from the last year or two? I've always had windows, but could always be persuaded to a Mac.
