The problem isn't the touch screen then, the problem is that when the menu's hidden the waveform display doesn't fill up the empty space.
It is if the UI was changed to accommodate larger buttons for the touchscreen feature. According to Highvoltage's post that does not seem to be the case, though.

Regardless, that does not invalidate my opinion nor the other two issues I pointed out.

All in all it is just a matter of opinion: you said you prefer touch instead of buttons, while I prefer buttons if touch is immersed on such simple UI and is missing features I consider important - thus, it feels like a gimmick to me.

Seems to me that they installed the wrong color LED to indicate channel 1 - it has got to be possible to install a yellow LED in place of a green one.

btw, I love black test gear, this scope really seems unfinished though.

But, the main reason why I do not have this scope anymore was the unbearable noise from the fan.
Since Dave did not mentioned this in his review -or I missed it - may be this is a true improvement to the older version.
You did, he said it was similar to the GW, just a little noisier and the loudest of the 4. IIRC the Tek was the best.

It seems like they kept the annoying "features" of the LeCroy scopes, Trigger level indicator, (or lack there of) and wired menuing but ditched the statistics and mesurment functions. 

Not sure what you're talking about, as LeCroy scopes have had trigger level indicators since the beginning of dawn. Plus this scope is not a LeCroy design, its an Iwatsu rebadge (i.e. it's designed and manufactured by Iwatsu), and its menu structure has very little in common with LeCroy designed scopes.

Hello,
   Thank you for the replies, I was digging through their e-bay shop just before this thread. :) What i men it the trigger level line, At home i have a 9345? (forget exactly which one) It struck me that it has the same "<-T" pointer but no line as well. Tough I take bask what I wrote about ditching the measurement stuff. I just didn't see it the first time through the video.

I had the predecessor, the Wavejet 354 (without Touch) and the screen layout really has not changed much at all. It seems this scope is the same as before, just with added touch.
The lagging of button response when the FFT was on was also present in my 354.
Interestingly, the one I had, came with a light and pleasant outside color.

In what year did LeCroy switch to black case anyway?

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!   :)

It started around 2008 with the introduction of the WaveSurfer (M)Xs-B and the WavePro 7zi.

Wavejet Touch 354 has a very bad DPO performance for the price. It is worse than Rigol, Siglent, or even that obsolete Tektronix DPO2000B from year 2008.
Agilent 54622D was also better at DPO. https://youtu.be/aVNfFewFn_Y?t=14m38s

The replay function is too simple. There is only manual scroll.
