I've made a tidy sum for years helping people get their systems set up. About 10 to 15 pc's a week. They drop them off at my office new, and I install everything they need including office, which I often purchase for them, transferring accounting software, data, photos, and other freeware/open source aps, and paied for applications they provide me licenses to.
Windows 8 goes and fucks this all up. I can with windows 8 still bypass the stupid Microsoft account, but with the new office no dice. I either have to register my customers software under my account which to me is stealing their software, or ask them to set up an account (which to them is hard, that's why they came to me to begin with), so I have 3 copies of office 2013 home and business sitting on my desk that I'm stuck with now, because I won't install them on a customers computer. I install Libre office, and tell customers they have to purchase and install office themselves because of problems with licensing. I also tell them that I have installed a good free office software, and they might want to give it a try before buying office.
The thing about google is that there is co-BENEFIT to signing up with a google account. Google backs up my android settings, automatically backs up all my phone photos to G+, allows me to use google apps, a nice synchronized calendar, a place to buy applications or download free applications that are vetted to be virus free, and I can turn all of that off if I don't want to use it. With Microsoft I see almost no benefit whatsoever except for them.
