JPortici:
after just one year? a scope ain't no smartphone
(they did release the mso version a couple of months ago though)

Yep. I downloaded 1.28 (25 apr 2017), and indeed, the baud rate menu is easier to use, allows more different "standard" settings, and once selected, allows fine tuning of the baud rate. Much, much better.
As a second scope for portable use, this is a really nifty one, and for a new scope, pretty good bang for the buck.
BTW, it looks like they do have a newer offering. It doesn't seem to be a new iteration, but rather it offers the MSO and signal generator options.
nctnico:
Hmmm they released a new version. With 2.7 they already made a lot of input easier if you press the select button again. Today I needed a 1 second trigger hold-off and that was much easier to do with the list of presets than spinning the variable knob ad nauseam.

Considering to buy the 70mhz version for audio preamp/opamp etc work.
However the manual lists the fft horiz scaling as 10khz/div minimum, which would mean that audio freq response would be squashed within 2 horizontal divisions! Making fft unusable for audio frequencies..
Is this true or am I interpreting this wrong?

I just tried and it is wrong. The minimum frequency depends on the samplerate so you can go down to less than 1Hz/div on long time/div settings.
