Tax pros care about speed even more than consumers, but I'm not sure there's a problem with that. It's just a different mindset.
I find it odd that there are no free online tax filers in the US? TurboTax has a free version in Canada, and some competitors do as well. I like the idea though. Tax filing can always be made easier.(nevermind, a quick search shows that both TT and H&R have free filers.)
