Wasn't aware chromebook is drived by a 2 cell only battary.
When I say a laptop like chipset, I didn't mean it's functional like, I mean it's packaging。 I believe the size of Exynos 5250 in chromebok is much bigger than in Nexus 10. I believe its for some reasons: cost, performance etc. What I hope is since more powerful chipset is being release, we could put such a small whole chipset - like a phone without screen, without battery, only mainboard and chips - into a laptop body and give it a 10 times bigger than phone battary. Then same performance but a dramatical long battery life :)
