I 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.
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 512Gb
