Hmm... but does it taste good? If I'm growing my own tomatoes, I'm going for something delicious like a Pink Brandywine or Cherokee Purple (which, compared to this specimen, is admittedly more brownish red than purple).
I just picked some of my first Purple tomato harvest the other day, they taste identical to regular cherry tomatoes (according to both my mom and me; I will be giving a few more from the second harvest to some other friends and coworkers).
