I use Linux since Ubuntu 8.04 LTS, the key factor that drove me to use it was Windows Vista, it took about 3 minutes to start on my laptop, while Ubuntu did the same in less than 50 seconds.
I have been using both since then, but i preffer Linux for mostly Web, however, Windows is still needed with my printer, and some peripheral as you have said.
Honestly i think the only way to suppor Linux is buying Dell Ubuntu products, that´s our only chance.
