Randy: "What's up, dawg?"
Simon: "I'm not being rude... but will you shut up?"
Paula: "You're so mean, Simon."
It's difficult to find a name that hasn't been used before! But here's a possibility... "Devoted to Macs."
No website has taken the domain name devotedtomacs.com, .org, etc. And I can't find any site called "Devoted to Macs."
