Will be going to uni soon and will buy an Air for my studies. 13" 8 256 i5 - £1039.20 with student discount My query is with using MIcrosoft Word and it lagging with this setup. On a PC I use Word as it is so spell checker, auto save and whatever else. I'm vaguely aware Office suite is a big and possibly not very efficient software package for Mac. The i7 would increase the price to £1150.80 which is fine for me if necessary. Oh and Internet scroll lag would be annoying too. Sorry to raise this i5/i7 question again but I don't really know the software often mentioned in those threads when used to describe user experience. Thank you.
