You haven't included the time it's taken her to go out and buy Windows and
Office. Lets assume it's an online purchase as local shops probably won't
have OEM versions for sale (also, as she's not buying any hardware with
Windows/Office to justify the OEM license, the OEM license is not valid; we
really ought to include the fine for running unlicensed software if we want
a true comparison). So that's (being generous) 2 days lost productivity at
$25/hour = $400.
Time to install Windows:
Time to install all necessary drivers (including reboots) and configure
basic networking etc.
1 hour - and your system is now completely vulnerable unless you add the
cost, and time, to install a firewall and anti-virus software. You should
also download all the MS critical updates (about 3-4 hours on a broadband

Included in the above.

Why? You've not included the time it takes to get it working in the Windows
setup? I would expect Linux to detect and use it without any problem,
although I've never used a Travan.
> Restore backup of data - nope, used Tapeware for backup
Again, you have not included this in the costing for Windows install.
And if you don't even know what you used for backup, what hope is there for
you? Besides, there's no need to restore the data, Linux will quite happily
read it from the Windows partition.

As with all "comparisons" I've seen of Windows vs. Linux "true" costs,
you've managed to conveniently ignore the true costs of Windows.
