it wouldn't be 'ironic', which is a word that has been more misused than any other in the last 10 years or so, however it would be slightly amusing.
None of this will make any difference to A.Dumbass though, who will do what they are told regardless, they get windows, and that's it.
Go on the internet? use windows
send email? use windows
write a letter? use windows
draw a picture? use windows - oh! windows can't draw pictures very well, i'll buy some program to do it.
Anything the OS can do (in a half or no assed way albeit) people will not buy any other program to do it.
Buying, downloading or installing a program is mystical and alien to these people (well maybe not buying, but once they've bought it, how many get a friend who's "in the know" to actually <gasp!> install it?) and if windows comes with a browser, a firewall, a calculator, an email client, and much of the time "comes from the shop" with Microsoft office installed, then those morons will never use anything else no matter how much better the alternative may be, or how shit the thing they're using is. They actually hate being told how shit their software is, because they feel some protective need to think they got their money's worth.
morons.
