Almost all high-end scopes these days come with touch screen, and that is for a reason, which is that touch allows users to work with the many and often very complex functions on these scopes without requiring a mouse/keyboard connected (which usually would be a pain on the bench) or a front panel with 600+ buttons. When combined with a good UI which has been designed for touch control like MAUI touch allows for easy manipulation of relevant parameters without having to wade through endless menu layers.
Fairy nuff. Personally, what I want from a scope is a high quality analog front end, high quality ADC conversion, a good screen and physical buttons - and an output port for exporting data to a PC so I can use a nice big 28 inch or better monitor, mouse, and keyboard for deeper analysis when needed. There are dozens of applications and graphics packages for PCs that blow away pretty much any scope, irrespective of price. Even Excel can be a surprisingly good tool.
...maybe not all touch screens are glossy mirrors on which fingerprints stick like on the gluey side of transparent tape? Most touch screens on industrial and T&M gear are matte...
I have been doing photography for too long, I guess... a fingerprint on a beautiful picture is just... wrong!
