Floored today with the experience of a +Dell
with preinstalled +Ubuntu
It was cheaper than the same thing with Windows, had fewer annoying stickers (it did have a Ubuntu sticker, but no need for a licence key sticker, ...), booted quite fast, ran a customised first-boot wizard (which was basically the same as Ubuntu installation wizerd, but with a couple extra Dell-specific steps) and then it turned the webcam on so the owner could either pick one of the ready-made user icons or take a picture of their face in one click and then it capped the whole thing off with a cool video version of the Ubuntu experience presentation.
Everything worked out-of-the-box: keyboard with all the special keys, video, sound, webcam, wireless, wired, ...
I was floored and in awe. I want to say great thank you to eveyone involved in creating this - from Debian developers creating the solid base, to Ubuntu developers bringing their vision, to Cannonical driving the business case and to Dell seing the light and giving this great option to us, the consumers.
I could easily recommend my mother bying a Dell with Ubuntu and be 95% sure she would be able to start working on it without my help. I did not think that was a possibility this morning.
