I'm waiting for he reviews as far as battery life and noise. If not much different, I'll be exchanging my i5, Iris GPU in Surface format is very intriguing, and I did't realize that Best Buy will carry the i7/256Gb version, a lot easier to stomach than the 512GbI preordered SP4 I7, 8 GB RAM and 256 GB SSD storage.
Logic: i7 to last into future requirements.
I am not sure how 16GB RAM will help me since I am not a gamer.
256GB because I store very little on my device and use the cloud a lot and backup hard drives
I ordered the keyboard with the fingerprint.
I also ordered the new Dock.
I also bought the extended warrantee.
Will need to get video output cables for my monitors.
I was using a SP1(purchased Feb 2013) which Microsoft recently replaced free of charge with a pro 2 because mine was having difficulty and they couldn't fix it.
