Refreshing to see a real world user and some real world comments. XP was stable after a couple of service packs, slow nowadays, because of no multi threading and we have to take Microsofts word that it would never have touchscreen, VR and the rest of todays / tomorrows tech. That leaves win 10 for the Microsoft future, designing your business plans around win 7 is ridiculous. For Apple your business plans are definitely maybe in the future, the no diy upgrade is not good for home / small business use ( not sure how upgradeable surface's are though). Only issue is waiting for better tech, if so neither Microsoft nor Apple will be cheap so better save up whilst waiting. At least with MS there are other hardware companies around.
