Summary:
Paragraph #1: Blah, blah, blah.
#2 - Fact (AFAIK)
#3 - Opinion backed up with nothing at all.
#4 - Perhaps there's something wrong with your Win7 box?
#5 - Win7 was head and shoulders above Vista yet it's the least impressive of the three PCs you own. Author doesn't notice the obvious logical disconnect between paragraphs 4 and 5.
#6 - Opinion backed up with nothing at all.
#7 & #8 - Opinion backed up with nothing at all.
#9 - People grudgingly complained about Windows 8, yet there's an air of passive acceptance regarding Windows 7? What has the author been smoking?
#10 - This guy is a tech author? He seems to need technical assistance from the average teen (not being able to figure out how to connect a Vista machine to a wifi network, it's hardly any different to XP in that respect either!)
#11 - This guy hasn't figured out the Win8 full screen app rationale? How about MS Surface and other Windows tablets? What an idiot.
Vista apparently got a bad rep due to MS's arrogance, but he doesn't specify how exactly, or how Win7 is worse.
