That's a rich person's problem, along the same lines as "You might get a headache from all the expensive tequila you sip as you relax on the beach with millions of dollars in the bank." I'm not sure it's actually profitable to worry about this even in the long run, and certainly not before you even launch. As long as "getX.com" works for marketing purposes, it's better than choosing something weird and unpronounceable.
