I have a desktop (a bit long in the tooth, but serviceable), a laptop (my internet Linux-based computer that I face when I talk to you guys), a netbook for traveling, and a iPhone for checking email (primarily) at work and getting the odd text or phone call from family member asking what's for dinner tonight.
Each serves a purpose. None replaces the other. Whilst I can run P7 on 3 of them, it runs best on my dinosaur because I can see it best (big screen). I don't see any one as a replacement now or in any sort of future, any more than a loveseat is a replacement for a dining-room chair: each has a specific purpose, and does not lend well to any other purpose, really (ever made love on a dining-room chair?? :lol:)

Wir sind gewohnt, daß die Menschen verhöhnen was sie nicht verstehen
