It seems to be a little biased towards Windows, at least the different "features" he is comparing. But a well thought out review none the less.
Installation - If this section is biased towards windows, then you've proven one of the biggest complaints about Linux. However, it's not, because Linux distros have come a long way with regards to installation.
Hardware and PnP - Uhmm... if this is a bias towards Windows, Ubuntu's got problems. In fact, Linux in general does have issues with hardware support, but I find it wrong to consider this comparison biased just because Linux doesn't support every piece of
hardware under the sun.
Software installation - Since you brag about apt, I guess you don't consider this one biased.
Word processing - Since Windows doesn't come with anything other than WordPad, I'd say this was biased towards Ubuntu. If he hadn't dinged them for the fact that Office is a separate purchase I'd have a different opinion. But then, in that case I'm sure Vista
would have one this category easily.
Indexing/search - Maybe a Vista bias, since this is a core feature of Vista, while it's just an add-on program for Ubuntu.
Multimedia - Since this is the #1 thing computers are used for, if Ubuntu can't live up here then it simply can't live up, period. Can't call this one a feature that leads to a Vista bias.
Image editing/picture management - See multimedia.
Backup/Restore - A core requirement for computers since the beginning. Don't think you can use this one for declaring bias either.
So, which sections lead to a Vista bias again?
