Hey guys, I have a 128gb Surface Pro 1 right now, and I like it a lot. But I was in best buy recently, and they had the Surface Pro 3, and I was really impressed with it. It fixed my major complaints about the 1 (battery life and weight) and increased the screen size effectively at the same time. So right now, I am debating picking up the 256gb i5 model, or a 256gb i7 model and giving the current Surface Pro to the girlfriend, or possibly even waiting for the 4, depending when it will come out and when they announce that. I've read that after a lengthy period of use that the i7 will get hot and won't run at full speed, and the i5 becomes faster, but I'm not sure if this is even true, or if there have been some firmware updates since. The Surface Pro 1 performs pretty well for me. I'm really wondering what the performance boost for the i7 is to the i5 and would it be worth it? Also, what's the battery life like on both?
