Having to take a loan to buy a scope for a hobby would be a giant red flag for me...

It was just about moment, here is the sale and only 3 scopes on stock in one web shop. The remaining two were sold out two days later. Not really wanting to wait for 5 years for similar promotion on MXO4 or MXO2 made me act pretty quick. I don't have any other loans, but my other hobby (woodworking) drains all free money from me. Free time is the most valuable for me. If only I could have all these tools and equipment when I had school holidays back then...

I'm not a big fun of Apple either, don't like closed systems... But, they were the first to put GSM modem INSIDE the tablet and add capacitive touch screen to it. That's why I bought iPad1 right away when I saw it. To put it to perspective, there was HP tablet with Windows XP at that time with stylus and GSM modem would have to be inserted into USB port... beh.

Speaking of steep learning curve, it took me a few evenings to actually compensate probes properly. RTB2000 actually shows you how to connect probes as picture on the screen... but I was blind to see. Probe has to be connected without cap and without ground wire but directly to calibration output. Otherwise, there were too many oscillations and higher noise. RTB2000 has a guide or "wizard" on probe calibration with real time assessment of how good it is set. Looks very useful to me, training wheels :)

Also ground has to be connected closer to the probe point, not to power supply output far away with lots of current. Lucky me, my father is EE and I can ask him. When he saw my waves he said that probes are not compensated or oscilloscope is broken. That was a stressful moment, but it was probes and the ground (I connected only one probe to ground and far away).

Still looking for a comprehensive text book on modern digital oscilloscopes. Something like The Art of Electronics but about scopes and measuring and instrumentation. So far found some old good books from Tektronix and some very sophisticated on measuring. Need some sort of reference on how to measure, how it should look like and how to fix the wrongs. One more reason to get a proper scope is not to doubt the instrument.

For desktops I prefer the custom build route.

True. I still find MacOS to be inferior to windows, overall. But it's super-optimized for the hardware.

This you can forget, trust me.
I´ve been looking for years for it, it doesn´t exist.
Although all manuals are written in such a way that one obviously assumes that the user knows how a DSO works.
Examining white papers and knowing about digital signal processing seems to be the key.
And white papers you can get from all big brands, but also from siglent.

As a beginner it is a good idea to have peak-detect enabled by default. That will prevent from becoming surprised by aliasing.
