I do have a small laptop with Windows 8 on it.....it drives me round the bend!
Like you I started in IT when IBM's smallest computer was a box the size a car and Bill Gates was still wearing short trousers (exaggeration

). First I was writing programs in Cobol and Fortran on DEC systems using punch cards, then in sales and support of peripherals. Then along came the IBM PC and Microsoft. Apple at that time were producing things that were not much more than toys for home computer enthusiasts.
The first thing I had to do with an Apple was the ill fated Lisa. It drove me nuts trying to get a printer to interface with it, in Port Moresby of all places.
perhaps that experience has permanently coloured my relationship with Apple products but what I can not understand is just what it is that people find difficult about Windows 8. For me 8.1 is very similar to previous versions, works better and faster, and is free from problems. I took me very little time to come to grips with the differences.
