Hello,
I want to start a small website focused on buying used Macs, any ideas for a domain name? I don't know if I can use the word 'Mac' because it is a trademark of Apple, Inc.
My last response was (somewhat, but only somewhat...) facetious.
What will your site offer that ebay or craigslist doesn't?
And just what do you mean by "focused on buying used Macs". It's not clear if it's matching buyers and sellers (like eBay/Craigslist) or offers advice like how to get the best deals, what to watch for, etc. Or are you interested in buying used Macs from others, like the sites that buy used phones? Or something else?
Hard to help name something when you don't know just what it is.
On trademark, you need to talk to an attorney. One that knows the consumer tech field, to boot. Some companies let it slide. Some let it slide with specific criteria. e.g. not sure if this is still true, but Microsoft many years ago drew a line in the sand, not allowing e.g. Windows Widget but allowing e.g. Widget for Window. The "for Windows" moniker was given some kind of blessing by Microsoft.
Once they've allowed something like that for long enough, they give up their trademark rights by not enforcing it. For Microsoft now to go after "for Windows" products probably would not be successful.
But IANAL - you need a real one!
