It is, but, well, I guess I'm just a weird nerd... you can buy the same (new) electronics at pretty much any Yodobashi Camera store, and if you're not heavily into action figures, anime, or porn, than there isn't much else in Akihabara, in terms of food or nightlife.
It's a fun shopping day, but if I was going to spend a week or two in Tokyo... well, I'd go to Osaka. But failing that, Shinagawa and Ikebukuro have better dining, Shinjuku has everything, and there's a ton of restaurants near the Tokyo station.
Although, if you want good food, and you don't feel like paying for the 'atmosphere' of a high-class restaurant, stay somewhere near a major university (Waseda, Tokyo, or Chuo). The restaurants all cater to students, which means they're cheap-ish, but not so cheap, that the quality suffers.
