The vibrating alarm clock that "wakes you at the right time" has been a big feature that only the Up band has really had over the years. Finally other wearables manufacturers are catching on!
@sleumasm@benburns I should have clarified -- the killer feature, to me, is waking you up with that vibrating alarm at the lightest point in your sleep cycle, instead of at a specified time when you might be jarred from deep sleep. I didn't think anyone but Jawbone had that previously, but I might be wrong?
