For the fun of it, I made these calculations on Windows XP and Windows 7...
My XP did in total cost me kr. 0,08 per day in use, that's some $0,0155 per day.
Windows 7 have so far cost kr. 1,20/day, that's $0,23/day and it will keep on falling for each and every day ahead...
For comparison I made a rough calculation on gear used...
On average until now it is
not less than kr. 24,35/day = $4,70/day
Which actually still is
very cheap.
Estimate on smoke per day is some kr. ~120 = $23...
Of course not having a car is a big help... try do the math on such a thing...
