Makes me wonder about the economics of producing these things. Apparently something related to the OS choices makes it worth Intel's while to develop separate models and the infrastructure to build each one, rather than just building the higher spec model and slapping either OS onto it.
It's things like this that hearken back to the glory days of the Evil Empire, and why people find it difficult to trust MS now.
Well, I can't speak for the Ubuntu one, but I have a Yoga 2 10" tablet with Windows 8 with nearly identical specs, only the Z3745 processor instead of this stick's Z3735. The difference in CPU is not significant.
2GB of RAM is not enough for web pages with endless scrolling, such as Tumblr, or bloated pages such as Vice.com. Chrome sucks up the RAM, and when there is none left, things aren't pretty. I use "The Great Suspender" addon which saves unused tabs to disk and frees up memory, but even that isn't enough. We are past the point where 2GB of RAM is enough for even simple web browsing. Maybe Ubuntu manages the limited memory better, but based on how much Chrome is using, the OS choice may be irrelevent and these devices really need 4GB of RAM.
