I run Chrome with a lot of tabs open on my Asus Vivotab Note and I don't really feel the pain of having only 2GB. I'm one of those guys with bad habits about closing tabs.
The thing you have to remember -- Atoms are serviceable CPUs, but they're nothing like the Core series. If you're looking to do heavy lifting, you should probably go for a Surface Pro anyways.
Have you considered switching to Firefox, which is a bit more conservative with memory usage? :)
iOS is extremely memory efficient but it comes at a cost which can be quite high for some.
Now, granted, the OS does use more RAM has availability increases (I have 16 GB) however Chrome is a beast no matter what.
But 2 GB? And maximum 4 ? Just kills me inside. Way to ruin the device.
My home workstation has 32GB and I can remote into that anytime I want from every device that I own, so I tend to lean on that.
But of course, the sad reality is that the only reason there is a 2 GB version is so that they can have a ridiculous premium for the 4 GB version yet still lure customers with the low starting price point.
I wonder if, when the market has matured enough, that there will be honest companies making products that tries to make good mainstream products rather than trying to get away with whatever they can. There is no reason what so ever that there should be any high-end smartphone available for purchase with less than 64 GB of storage. But now we have 16 GB and, for a $100 GB premium you get, gasp, 32 GB!
Phone storage has not gone up, in many cases down, in the last five years... And that's like 120 years in the tech world.
But hey, 2 GB of ram is certainly enough for the 5 min demo you get in the store...
