Preordering a Pebble

Is it worth preordering a pebble? I'm a little apprehensive about preordering and buying something without proper reviews or a real launch window. Also the technology in it is a little dated and with rumors of Apple making a smart watch and Toshiba(?) showing off their product, I'm not sure if I'll be jumping on the whole smart watch train a little too early. I know that Pebble is announcing something tomorrow which should give me a bit more of an idea of when they actually intend on shipping or other things.
