Last night I briefly examined a heavy Dell laptop running MS Windows 7 Professional on an Intel Core i7.
The word that comes to mind: Ancient.
Good lord, having to deal with Windows is like falling into Mister Peabody's Wayback Machine and stumbling onto a stone age tribe of Neanderthals playing with sticks and fire.
If the zombie apocalypse ever begins, just issue them all Windows PCs to slow them down into obsolescence.
