That's a really cool device, even more so because it actually exists  :-+

But... I was watching that video and at 00:40 my internal alarms went off: I can just imagine standing up quickly, or just turning round, maybe even just answering the phone, and that's whatever the thing is plugged into on the floor. I can see a future involving long wires and recalibration of reflexes  ;)

While it's certainly a very neat device, the limit of 4 MS/s gives it an effective bandwidth of below 400kHz which really limits its applications to essentially audio circuits and the odd simple pulse gen.

Got a friend that has one of the other Xprotolab's.  The thing works GREAT for what it is.  We don't expect it to measure a 10Mhz sine wave or catch a 1ns glitch.  We've got other tools for doing that.  But, for the $$$, the size, the power consumption, etc.etc.etc., it's a great tool to have around.
Now, whether I'd actually use one in a wristwatch form factor...well, probably not, but as was said a couple posts ago, the fact that the whole thing is jammed into the watch body does deserve some cool points.
I didn't take it apart.
I turned it on.

The only stupid question is, well, most of them...

Save a fuse...Blow an electrician.

but as for things that really matter, like "what voltage is VDD"
The regulator can output either 1.8V or 3.0V, that is why I just show VDD.

It can, but does it? If so, document that. Split the schematic onto pages (or at least use a bigger page!) where there is room for comments, and add one. We comment code, why is commenting schematics so uncommon? :-//
