Decisions decisions. I'll be going desktop less soon. So looking for something to replace my current setup. Bonus of being something that could do some light gaming or take on a plane with me is a bonus. So will have to look.
If you're going to get rid of desktop PC and as you mentioned also running VM you should get model with good amount of CPU power and 16GB of memory.
(especially when memory is typically soldered in compact/lightest devices)
Especially older models have might have only dual cores.
There are now also quite good number of "convertible" laptops with display turning 360 degrees.
If you're basically replacing desk PC and know you're going to use keyboard constantly, I don't see much sense in "tablet first" device.
As for gaming integrated GPU's are only good for either old or low requirements games.
And anyway devices meant for good portability rarely have more powerfull separate GPU.
Tablet first devices with just separate keyboard certainly don't have much of room.
IMO you should start by doing list of things you want most.
What are absolute priorities...
What "if possible" features...
Connectivity requirements. (like if you have external monitor)
Of course size and weight and price limits.
And then work on that starting point looking for various devices.
