USB stick, a bit of an odd decision... probably to avoid connectivity issues, its an easy solution- I guess.
they do mention USB wifi dongle on the forum... actually, it sounds like if you have some skills with Linux, you will be able to treat it as a Linux box, so do what you wish - but theres not alot of info on that side at the moment.
(e.g. it has a HDMI output, and USB keyboard/mouse... can you edit on the box itself? perhaps even just do a remote X session)
as for editing, well, I guess you prototype with PD on a PC/Mac first no... so only need to transfer when finished.
(Ive actually no issue with that workflow... has the advantage you can test without the board attached)
OLED... yeah pretty small, but I guess probably not far off the OP1 size, I dont think you need much, its just parameter,patch and menu selections.
Keyboard, seems to be part of their brand... again bit like the OP1, nice to have something you can play on the road... or when you dont want to have all your gear around. (thats why the battery power is a key missing element!)
Id guess opinions will be divided... axoloti is the ultimate hackable board for music, both hardware and software... perhaps the Organelle is 'less hardcore' , gives you the modular synth, but in a fixed hardware format.
Of course, I hope Axoloti Remote can bridge that gap, make it more accessible to those that dont have the time/skills for hardware hacking (and yes, are willing to pay extra for that privilege )
