I've been on the fence about getting an iPad air since it was announced.
if the revision comes out before August, has 2 GB ram. and GPS capabilities, I'm buying it.
----------
RAM battery usage is extremely minimal in comparison to everythign else in the device. They could easily throw in 2gb of memory and not impact battery performance overal.
Especially since the trade off of the low RAM is forcing the tablet to do more work when RAM becomes low.
For example, the pervasive tab reloading for many users. Everytime that tab has to reload, you kick off the cpu, and antennas and more data transfer. All of that will likely have a larger battery impact than just powering 2gb v 1gb.
if virtually all the competition has figured out how to put 2gb, and in many cases 3gb of RAM into their phones without impacting battery life, why is this a problem only for Apple?
