If the current trend of very large phones continues, the "it's easier than getting your phone out your pocket" feature might actually be enough of a pull for an entire class of wearables.<p>I've recently got a Nexus 6, and I have a bit of a love/hate thing going with the size. It requires two hands for practical use and (although still fits comfortably in my pockets) does take noticeably more effort for quick glances than my previous iPhone 4. But when I have to use it for anything more meaningful I'm glad for the decent screen size.<p>A companion device may be a welcome addition here.
Bit long winded considering the only advantage (I can see) that a watch gives over a phone is the length of time it takes to get a phone out of your pocket.
