So I finally picked mine up and had a quick test in the hotel room yesterday.
Very early impressions are that the screen is a major positive, about time someone bothered to put something of reasonable size and resolution in a sub 10k instrument! I'm sure this will also help with taking advantage of the 10 bit ADC, which is also very welcome (my first scope was 10bit, made the 8 bit rigol feel limiting sometimes when zooming into an already captured waveform).
Negatives are lag in the menus (especially scrolling) and those darn detents in the knobs. Touch screen thankfully makes up for the detents somewhat (moving traces is responsive enough to substitute for the knobs in many situations), but I'll probably buy a spare encoder or two to experiment on disabling the detents - they're unfortunately not available without them
One strange thing I noticed was that the waveform rate seems to slow for a brief time after changing any setting, before going back to normal - anyone else seen this?
I also grabbed the front cover before getting the scope - it's rather expensive for a piece of vacuum formed plastic, but fits securely, feels strong and I think it will protect the front well. Downside is that it's a bit of a fiddle to put on, but I think it was a sensible purchase given I'll be hauling it around in hand luggage. I'm most afraid of damage to the rear grill now, with the cover on it's now by far the weakest point.
