Are the new Fitbit models worth the upgrade?
The Bluetooth connectivity on the One seems like a no-brainer. You won't have to bring a base station on trips to sync up anymore, just your phone. But as for the vibration, is that an appealing enough feature? I was surprised last year by how many people wanted stairs tracking (though to be fair, the Ultra is also more accurate in step-counting than the Classic). Do you like vibrating alarms? Is it a feature you want on your fitness tracker? Did you buy a Jawbone Up for this reason (and were you disappointed by its overall performance)?
Personally, the vibration won't do me much good, it seems - this morning I woke up to discover my Fitbit had fallen out of the wristband, so a wake-up vibration would have been rather ineffectual.

Anyways, the vibrating alarm is nice but not worth upgrading for me. Bluetooth is an awesome feature but since I have a base station at my desk at work and at home I rarely have an issue with getting synced up. I just wish they would improve the sleep tracking feature--it's really not useful as it is now and it only needs a software improvement. I'll definitely look in to upgrading if/when my Ultra wears out but for now it still works just fine.
EDIT: I'm also a little skeptical of the Zip. I understand wanting to have a budget model available, but (1) Bluetooth 4 is only available on a handful of devices so far so only people who are buying the latest phones are going to be able to take advantage of that for now, and (2) people generally hate replacing button-cell batteries in their devices; in fact I'd wager that when a button-cell battery dies there's probably a lot of people who never replace it or just throw the device away rather than figuring out where to buy a replacement.
The vibrating alarm sounds interesting and I'd like to see how that works as well. If it works well enough then I may be able to just ditch my alarm clock! :D
The vibrating alarm is the only good feature of this new one.
The Zip is just dumb. Basically just intended to be a cheaper and junkier version that you gift to someone for Christmas. As soon as the watch battery dies in the Zip 4 months after Christmas they'll put it in a drawer and probably never use it again.
I don't mind the docking station either, at least I always know where my FitBit is when I'm ready to leave the house!
Anyway, here's the link if it helps anyone else:
I like that they have finally put a more prevalent communications technology in the Fitbit One that shouldn't require an always plugged in dock, but at this point I have enough docks that sync frequency is not a problem (work and home -- from my classic and ultra).
Ultimately, unless there is some new tracking feature (vibrating alarm might not even work for me as I wear on my waist at night) or I get a new computer/phone with BT4 I don't see this as a worthwhile upgrade.
