I digress on the TLD part. If your users are DESKTOP users, TLDs are not so important. If they are mobile users, they can type ".com" on their on-screen keyboard. If they don't remember the domain, they will go to Google and you might have some trouble with people advertising on top of your #1 positiom... ... which will happen only if you're successful, of course. I totally agree on this: you should focus son the product, not on the name. People will buy your product - name changes are more frequent than we think.
