W7 is the more stable OS.
I’m surprised at that to be honest. My last Mac desktop ran continuously for about 5 years and maybe rebooted it once every couple of months at most – usually after a power cut or the occasional Microsoft Office glitch. I honestly can’t remember the last time a piece of Mac software brought it down.
As for high end work PCs a totally different story. Daily crashes the norm, shit software all over the place, shit memory management, hard drive failures, RAM issues, graphics card issues, network issues, etc, etc. A complete pile of frustrating shit. That’s why I always use Macs at home. Not because I’m a fanboy, but because I find they work a lot better. I’ll make do with a PC only if I have to.
