Thanks for the responses, everyone.
I have actually decided to return the i3 and I got the i5/4GB/128GB model. I have been struggling between the 4GB vs 8GB and i5 vs i7 for a while now. And, I have been struggling to find a tablet. Since I came to the conclusion that I am not going to buy a system for work (web development/design/graphic design and I figure if they want me to have a faster system, they are going to have to buy it for me or at least meet me half way on the price), and I am going to use it mostly for strictly a entertainment consumption tablet, that the i5/4GB/128GB was the sweet spot for me.
I also bought the new Microsoft mirror cast dongle. It seems to work really well up to 20 feet away. That eliminates a need for a display port adapter and an HDMI cable. I just thought I would throw that into the thread in case anyone was looking at it.
Am I right in assuming that the 4GB model will be fine for future tablet use? I mean, I don't see any time in the foreseeable future that tablet use and apps are going to run out of the 4GB of RAM...I think.
