Android Wear devices are finally out in the wild, and while we're all still waiting on the Moto 360, the Samsung and the LG ain't bad. The folks at iFixit tore them apart to see what's underneath the surface, and what they found was mostly what you'd expect. With one exception.
Both the LG G Watch and the Samsung Gear Live sport 4GB of RAM and the same Snapdragon 400 brain, and according to iFixit, they're remarkably easy to repair as far as modern gadgets go. Basically no glue! So if you need to tinker with your smartwatch (a real nerd's nerd, aren't you?) then you should be in luck.
But deep inside the Gear Live there's a secret Wi-Fi antenna. The Gear Live doesn't support Wi-Fi connections (yet) but maybe someday it might, although it'd be pretty worthless without a phone to tether too. Meanwhile, the G Watch packs no such surprises.
