Windows 8.1 like Windows 8 is a pretty solid OS. Contrary to what all the haters say it is a really solid OS. Having said that for non touch screens it offers nothing over Win 7. Win 8 is basically Win 7 with touch features added. If you are happy with Win 7 then Win 8 will not offer you anything new. The desktop experience on Win 8 is by and large the same as Win 7, except for the lack of the start screen which you will get used to in time.
