I guess if they would sell a single one without making it easy for hacking, it's like a tradition by now
Or they could issue a special "Collector's Edition" that disables "hacking" just so that people justify buying a 2nd one...
I think TE manufacturers completely mis-understand their market. They keep adding features, more decoders, more bandwidth, lower noise, etc... when all they need to do to keep most TE users happy is come out with an identical model, but in a different colored case, every couple of years. TE users are like Pokemon players - "gotta collect 'em all." I can just see it now
"Hey, do you have the Rigol DS1054Z in the yellow case yet?"
"Nah bro, but I did get one of those pink Siglent SDS1104X-E's though!"
"Cool, man, I gotta get one of those!"
