I really have the itch to pot tomatoes. They will not get transplanted to the garden until May, but I can transplant to 4" or 6" pots as they grow. I'm thinking the ability to transplant to 6"should give me a longer window to get them started and that might result in stronger, thicker plants to put in the garden. With only having until August to harvest tomatoes in prime weather conditions (heat), I often throw so many underdeveloped tomatoes into the compost pile. Perhaps trying this new concept of extra early (by 2 added weeks) starts will get me tomatoes sooner, meaning more overall yield as they continue to produce - at least for the indeterminate ones, but I'll start the determinate early too just to see if they yield faster.
a neighbor of mine has a small concrete courtyard. she grows tomatoes in pots and they are fine. you that live in a cold climate might consider growing a few in pots so that you can move them inside after august when it gets cold.
