Over the course of the three months I've had this laptop, it's had (at least for me) major problems twice. Also, it LOVES to restart at the most inconvenient times and it's fairly slow.
On the other hand, my 2008 Mac is fast (as long as I don't have too many tabs open), complies more than my new laptop, and has only had one issue so far, which was a little malware that, in all honesty, was my fault. Oh, and I've had it for about a month more than my new laptop.
