In one interview, available somewhere deep in Youtube, one of their engineers said, that it takes around four hours from their staff to assemble. From him it took seven hours on first time. 

I think it took me around double that, but I'm convinced I could halve that if the parts were better arranged, de-bagged etc. I would imagine that the engineer who did it in 7 hours first time had plenty of space, all the parts sorted etc.

I swear I spent half of that time searching through boxes and bags...I enjoyed building it, but it could've been much more enjoyable if each section had its own parts divided up separately.

This was the first printer I've built from scratch, and definitely something I'd like to do again.

Phone method didn't work for me - gave me readings all over the place. Only got it to work briefly. In the end I just went by feel. Luckily it looks like I got it close enough as all works perfectly!

I have some minor improvement recommendations. Any machine subject to vibration, where parts are assembled with machine screws into metal, aside from screwing into a lock-nut, should use non-permanent thread-locking compound to avoid self-loosening.

Attaching the right side panel handle with the filament sensor was quite a fiddly chore. Trying to hold the panel to the frame, keeping a small button-head hex screw on the end of a screwdriver while aligning the screw holes of the filament sensor was quite a challenge. I ended up turning the machine onto it's left side to allow the right side panel to sit stable via its own weight without the tendence of the screws to fall and bounce to an unreachable area. It was also helpful to use painter's tape to hold the handle in position until getting one of the screws started.

It's easier to tension the XY belts before attaching the upper acrylic side panels. Not the adjustment itself, since those screws are easily accessible at the front, but checking the belts acoustically using the app is easier done from the outside of the machine vs trying to reach in through the door opening.

I just had an issue with the nozzle scratching my heat plate in the far left corner. The cable cover for the heat bed was raised too much, so that the Nextruder fan shroud would touch the cover before the nozzle would touch the bed. I assume this messed up the meshing algorithm (some interpolation of the exact bed coordinates, I guess?).

Anyway, the reason for the raised cover was clearly the M3x10 screw (cylinder head) installed according to the instructions. I exchanged it with a spare "rT" screw of the same length. Maybe someone can check and confirm this. You can move the Nextruder into the far left position and see if the nozzle can touch the bed or not. This may require to rotate the Z-rods by hand.

This is now fixed in the assembly instructions. I built the kit last weekend and there it still was the cylinder head M3x10 - with this comment in mind, I already put the flathead screw in the heatbed-cover.

If you check the manual now, its an M3x10rT -> HERE

So, it's evolving - even the version numbering hasn't changed. I would like to see any changelog or something, so I could check regularly if crucial changes like this one were made so I can check my printer...

 It took me a long day to build my kit - taking my time and going carefully.  Obviously the Prusa staff will do the job more efficiently, but I'd be surprised if one person could build more than two in an 8-hour day.  Even if it's a production line arrangement where one person does nothing except, say, the base assembly all day, the aggregate time for a build might work out at 2-3 printers per person per day.  So kits make a lot of sense in terms of getting a lot of printers into customers hands.  It probably pays them to make sure it's an enjoyable process so that enthusiasm for the kits remains high.
