I've been using macs since 2006, love the OS and can't imagine working on a windows based PC on a daily work stuff.
Own iPads, iPhones, iPods, apple tv, airport express, macbook and macbook pro.
Meanwhile my media player acer revo runs on windows 7 with xbmc, takes at least 7 minutes to boot, windows 7 known bug, unresolvable
Few days ago I got a Nexus 7, love the android 4 for the in-car pc stuff, navigon and sygi, soon the tomtom, torque and so on, but I can't imagine using it like I'm using the iPad, it's way beyond the iOS5, talkless iOS6...
Never had any problems with Apple products, you open the lid on the macbook, start working, no crashes, no restarts, uptime it's few months, unless restart is needed after system upgrade, you finish work, close the lid, all perfect. No defrag, no antivirus, no BSOD, no windows not responding, no windows has performed... and will be shutdown, etc
How can I not advocate products that never failed me?
