I have the same problem living in Alberta, Having localized darkening on the windshield for the horizon-level sun would be great.
And no, sunglasses don't help. If you've ever driven with the sun in your face then you'd know that.
Chrome is a better browser than anything else coming pre-installed these days, including Firefox 3.x. And I find it funny you noted Adobe Flash player being installed. If it's not, the average user is going to install it in the first 5 minutes anyway. Pretty useful item in the post-1993 internet world.
Google Desktop I'll agree is a pain, very slow, very useless.
Ubuntu is a desktop operating system. Joe Blow doesn't care about anything you've posted. And if you're considering Ubuntu for anything but a desktop computer, then you're doing it wrong.
