Thanks to the merge of gspca drivers, the next stable Linux kernel, 2.6.27 will support most web camera available on the market nowadays. These drivers will support many devices and it will be added in the future (remember, new drivers are being added constantly every cycle, mostly in merge window).
Even though i don't have web camera yet as of now, this kind of work will make me measier to choose which product i should be in order to work in my Linux box in the future (when 2.6.27 shipped, which is about 2-3 months from now).
Future laptops should be more functional, as more and more drivers are included in the kernel, so most of the devices should work out of the box after installation process. This should make switching to Linux become easier.
