Yes, it does seem reasonable to allow the defendant more choice on where they have to go to court.

Is there some hack around the East Texas problem? If you don't sell your product in that area, would it be possible to avoid being brought to that district's court? If so, I could imagine companies could simply have a notice on their checkout page: "Sorry, you live in East Texas, we don't sell there". I'm sure some companies would not want to leave money on the table like that, but for many things I do, I'd be happy to take such a position.
