Im a bit unsure about the 4gb Version, i mean i cant imagine a usecase, where i would need more than 2 gb
I wants to Play Minecraft on Pyra, which could need some Ram, but most thinks will be a bit of webbrowsing, Youtube, write something on the goo via Libre Office, mybe use Gimp for some low level trawing ( .., - and ready is the moon face).. play around whit DVBT, listen to Webradio, and make lots other tings i also made on Pandora..
My interests in Emulations are Dreamcast and PS1, and DS, and most of the Time SNES, GBA, N64 and Genesis/Mastersystem and Atari..
Ports up to Openmorrowind and Doom 3, but thats it, ..
I dont know if i need more than 2 MB Ram..
But on the other Side; on my CC Pandora, i was at the low end of the Pandora Performance, somethimes i feeld a bit anger for the Rebirth and 1GHZ Users when my Unit runs out of Power for some tasks..
So maybe i would get me a 4gb Edition if the energie consumtion isnt that diverent..
If the Diverents are 15 Hours 2GB and 10 Hours 4GB, i wouldnt buy a 4GB, but i wouldnt bother about + - 1 Hour..
