I would go with Win7. I just installed Win8 today and quite like it, but Win7 is very good and unless you feel Win7 is inadequate in specific ways compared to Win8 then it is not worth the trouble to get used to the new interface. By the time Win9 comes around the interface may be very different.
(For me the key features of Win8 were: improved internal parental controls, which were malfunctioning for me on Win7; ISO mounting, since daemon tools was giving me some problems in Win7; better UEFI support and a few desktop tweaks.)
-It is metro only, so not suitable for desktop.
-It is lacking in features compared with other PDF readers.
-The display of text is terrible.
In PDF readers, there are those who have good text display (Adobe Reader, now joined by Foxit), and those with bad text display (all the rest as far as I am aware). The difference between the two categories is the presence (good) or absence (bad) of sub-pixel anti-aliasing. Just look any two side by side and the difference obvious.

The built-in PDF reader is no good because:The in-built PDF reader sounds like a good idea what with Adobe's security track record , though SumatraPDF works for me.
