Where will Oscilloscopes and DMM's be in 10yrs ?

As a hobbyist and ham radio operator, I very much appreciate having access to instruments I could never, ever afford to buy with my own money. That said, the thread was about where scopes and meters will be in 10 years, and I do feel fairly confident a lot of the "higher end" innovations will trickle down into the more (personally) affordable instruments. I've been working in test and measurement for about 25 years now, and I'm perpetually amazed when I compare modern "entry level" instruments to "high end" instruments from a decade or two ago.

Despite being screaming fast (4.5M waverforms /sec) the new MXO4 is also whisper quiet - like, "is it on?" quiet. We're very proud of that :)
As a T&M instrument manufacturer, we get a LOT of feedback about acoustic levels: you might be surprised how important "quiet" is to a lot of customers. Over time, I think (audio) noise level is going to become a much more important differentiator when it comes to instrument purchases.

It's quite remarkable that we are hearing this from someone who works in manufacturing oscilloscopes. But the blokes above seem to have a hard time understanding ergonomics.
BillyO:
Getting back to the question, we'll see further capability and features make it into "entry level" instruments but the entry level won't change that much. Scopes will still cost $400, but they may offer 12--14 bits, 2Gsa/s or 200MHz and 4ch at the base level. On the DMM side we might see 5.5 digits and 4W ohms for under $300, 6.5 digits for $500. Along those lines.

Where do i see scopes and DMMs in 10 years...
Lecroy had a really expensive scope with detachable screen. I've read somewhere here that it was a disaster, but i think that will be one of the things of the future: a more than decent acquisition module coupled with a screen. Together they look like a scope, but you can separate the screen from the acquisition module and see everything and interact realtime via a really high speed radio link. Wired connection too, maybe. So what lecory tried, but better and affordable. Reason is bench space, having to insulate between the user and the DUT, DUT being not really accessible. An evolution of todays tablet/portable scopes
We already have wireless multimeters with some basic scope functionality, but of course you are constrained by BLE bandwidth and the fact that you're running an app on a phone.

I thought about that a lot. My only worry was (other than the warranty) that the plastic would break as time passes. If there is space for another metal laminate shield on the *inside*, I think it's doable and the plastic enclosure won't break.
Other random thoughts...:
I don't know how the airflow is directed in R&S scopes, but on a brand I know a bit better the fan blows from the inside towards the outside of the scope.
This has major disadvantages:
1. A smaller amount of air will blog through the components (perhaps contrarily to intuition).
2. The inside of the scope will have a negative pressure (that is, will suckle in air from any opening no matter how small). This renders filtering the fan vitually impossible. In time, dust and grime will accumulate upon the pcb, the caps, the heatsinks, the chips.. Thus reducing the thermal efficiency and the reliability of the instrument.
3. OTOH, a fan blowing towards the inside of the instrument can be easily filtered (just place a Demciflex filter on its vent) and will create a positive pressure into the scope, thus keeping dust&grime accumulation away.
