Your telling me, I went out to buy a new laptop a couple of weeks ago expecting to spend about 400-500 came back with a the macbook pro retina, all singing & dancing & nearly £2k over budget
But what a great bit of kit, the screen is awesome
I'm finding the screen a little over kill tbh, the fonts are tiny under linux!
I can well believe this, most of the OSX apps compensate for the high pixel density.
You running Ubuntu or another distro?
Fedora using WindowMaker rather than Gnome/KDE etc. Don't think much has changed with it since the late 90's and still find it the most productive window manager, so on modern hardware it's stupidly quick!
