Aspect ratio of oscilloscope displays
Kleinstein:
The modern DSOs tend to add extra information to the sides or top bottom. So a wide screen could have the exra info more on the side instead of bottom. So they can adapt to the screens available.
SilverSolder:
When it comes to screens, the bigger the better... my next scope will probably be a USB model for this reason, so I can use a 24" or bigger monitor with it.
Along with the fact that I usually end up importing data to the PC from the scope because that's where I work with the data, has led me to the conclusion that the USB scopes are worth looking at.
SiliconWizard:
As said, scope displays tend to follow the trend for other applications, for cost reasons to begin with. These days, a decent 16:9/16:10 IPS panel can be had for pretty cheap, whereas for a different form factor you will usually have to settle for "industrial" displays which can be VERY expensive. Back in the old CRT days, wide screens were very uncommon and would have been very expensive. So that's the cost factor.
As to usability, it really depends on your use case. If you're typically often capturing "digital" signals and want to analyze a significant portion of them, a wide screen will be better obviously. You'll appreciate having more horizontally, and won't care as much for amplitudes. But you may also want to analyze signals where amplitude matters more, and then you'll appreciate having more vertically.
Of course for specific uses, you can always either use some kind of USB scope, or just grab the samples from your scope and display them on a computer screen.

My two cents: I love larger displays, especially when coupled with higher resolution A/D's. But I have mixed emotions about the "wider than ten divisions" aspect ratios. While I appreciate seeing more of the time domain on the screen, it's darned useful to be able to make quick mental calculations using the timebase and knowing there are ten displayed major increments. My Rigol 4000 series displays 14(!?!) major horizontal divisions which makes quick-glance calculations nearly impossible.

In the past there was a push to use vertically oriented displays but it never caught on. LeCroy currently has something like that with a rotatable display.
