In on this!
Picked up the i3 version for $585 today with edu discount and movers coupon.
Awesome! Did they give you any problems with stacking the coupons?
Powercfg /batteryreport /output %USERPROFILE%\Desktop\battery_report.htmlI was hoping for a far better battery lifetime with the i3 version, however what I can see now is far from it. It's a pity.
What would be interesting to know is the capacity of its battery. Has to be lower in comparison with the i5/i7 vesions...
key take aways from the Anandtech reportAnand just released an i5 vs i3 battery life article. It's showing about 1 hour more than i5 (9 hours vs 8) for web browsing but for anything medium to heavy, it is only about 20 minutes more. Worth it? Not for me. Not a big enough difference to compensate the performance hit.

edit: misread the graphs. In the test outside of browsing, it seems the i5 actually has marginally better batter than i3. I5 has better battery when used in a laptop capacity, but as a tablet, i3 wins.
the Core i3 Surface Pro 3's battery life shows a slight regression compared to our Core i5 results but not significantly so:
Although our laptop tests didn't show any gains, our tablet workload showed a substantial increase in battery life for the Core i3 version vs. the Core i5 Surface Pro 3:
An 11% increase in battery life is likely due to the lower power binned Y-series Haswell ULx part. It's interesting to me that the gains are exclusively in our lightest workload and don't appear to be present under any of the more active workloads.
I still feel like the best overall balance of battery life, storage, performance and price is going to be a Surface Pro 3 equipped with a Core i5. I think where the $799 Core i3 makes sense is if you're budget limited and left with the choice between a 64GB ARM based tablet or the entry level Surface Pro 3.
