I had a look at the pagefile size Windows decided to set on my Win and it's only 256MB... which means in the 5 weeks I've had it I never actually needed all 4GB of RAM. That's with gaming, dev/compiling, web browsing, and even running a linux VM while doing the other stuff etc... i.e. more would be useless in most realistic cases on a device of this form factor.
TBH, I've never understood how Windows uses and allocates RAM. When one is researching, comments seem to explain that you won't need more than 8GB in most situations. Well, I had an 8GB high end laptop and my RAM was almost always touching the maximum and doing basic things (mainly browsing (albeit with too many tabs and windows), and spreadsheets), without entering in more multitasking, developing, VMs, etc... I then upgrated to a 32GB RAM laptop and doing the same kind of thing, I've seen RAM going to 13GB used already.
I think I would use a small device in a similar way, as some research takes time and I just put the devices to sleep so that I can carry on next day where I left off. The small factor of this device looked perfect for portability, but I wanted to use it as if I had a 'proper' PC, after all, it's priced like one.
If there's nothing else in the market (or plans to release something slightly with higher specs), pretty sure I'll end up buying this one. But I think I'll wait a little bit to see if there's some movement in the arena of mini portable PCS upto 7".
