I have an Asus (Model UL50V) from 2009 with an Intel Centrino- 4 GB RAM. It's my everyday machine. It is getting slow at many things (but a recent hack to Thunderbird settings helped a little). I dual boot Linux Mint 17.2 (Ubuntu 14.04 IIRC), although I haven't actually booted windows in years. I have a Toshiba Satellite for travel, windows 10, and in virtualbox I have a Mint system that basically recreates my work environment (which is usually Fluxbox). The one good thing about about using the old system is that using Virtualbox isn't annoyingly slow. I am looking forward to upgrading my work box to a linux-native desktop (System 76 or such) and joining the modern age! I was hoping to outwait Spectrum/<forgot other name> but now that is looking hopeless?
