2. There does seem to be an advantage to 2GB at the moment if you're running an ELEC variant on a cheapo amlogic box. People with 1GB devices are reporting freezes / out of memory problems. That's down to bugs / software not optimised though.

I am runing an ELEC variant and it runs absurdly well below 512M, in fact I have never seen using it using more than 256

Code:

total       used       free     shared    buffers     cached
Mem:          1494        194       1300          0         23         68
-/+ buffers/cache:        102       1392
Swap:            0          0          0

I haven't imagined it, honest guv.
Some people with 1GB devices are reporting freezes.
There's a fair amount of discussion in the libreelec and amllinux sites / threads about it.
Not surprising with so many different devices / so many different ELEC variants floating around.

Edit: just checked my box and it's using 563MB (33%) at the moment.
My xbox (64MB)and the first Pi I bought (256MB) are obviously a bit more efficient in that regard.
