And yeah, PT Cruisers are terrible.
I used/liked:
1. Show to people at parties/in social situations, people are very curious about it
2. Look at texts/email (and possibly fb/twitter, but I didn't want that stuff going to my wrist) without taking my phone out. Especially when driving with both hands on the wheel, reading short texts (one word/short sentence) was pretty easy (and not too terribly dangerous, I thought).
3. Configurable face is amazing -- you can design your own watch face, add widgets like weather, battery, bluetooth connection, etc
4. If you develop, it's great to at least have one thing on the platform, in case you decide to develop for it.
One of the negatives is the closed platform. Like the galaxy gear, Sony doesn't really make it easy for you to modify the hardware/low-level software, and there's the whole silly "get our app to communicate" business, which is just trying to lock people into a walled garden.
But all in all, the smartwatch 2 is fantastic, and it's got a great (non-prohibitive) price tag. I got mine for like $100-130 on Newegg Flash
