Yes, of course. I was only expressing my understanding of the offering. But I have no special insight...just an opinion...and not a very technically aware one at that.
Anyone happier after switching to i5 from i7?

Glad somebody did this. I always figured the i7 vs i5 would come out this way. Intel designed higher performing CPU & GPU that runs at a lower base clock rate (1.7 vs 1.9) with the same 15w TDP. If it came out any other way Intel would have failed. That's why they can sell the i7 for a higher price too.
I actually went from an i7 to an i5. I had initial overheating, thermostat of death, issues with the i7. After all the updates and about 2 weeks the system seemed smoother and cooler. However, I returned it because it had overheated a few times to the point of shutdown. I figured I would give the i5 a try. Had some initial issues with getting updates installed. I will say I have gotten the fan to kick on in the i5 about the same as the i7. This seems to happen with video encoding, goPro Studio, on both devices. Generally, the i5 seems to run cooler for me but I need to do more tests and the goPro encoding is the most intensive thing I generally do; 1080p 60fps videos about 30 min long each. I was going to exchange for a new i7, but I thought I would take advantage of the extra student discount on the i5 to see if it met my needs.
The i7 might have moved a hair quicker during the process, but hard to say as I didn't time or do side-by-side, but the i5 seems to still run cooler though only slightly. Not sure what my final decision will be. I will test more if MS happens to send me another i7, I asked for an exchange but they seemed to process as a return.

Thanks, I might go back. I don't know if it is related to the i5 but the surface actually goes into connected standby in the middle of encoding video which I didn't notice my i7 doing and when I wake it, it usually resumes but the video comes out half the file size and some quality issues though the properties all indicate it is okay. Also, I noticed I can set put computer to sleep never but can't tell it to just turn the display off.

I'd like to see a real study of the i5 vs i7 ... performance, power, heat, doing the same workload.
Just watching the Temp rise and fall almost instantly its hard to see why some statements are made. if I have 1000 instructions to execute and I get them done faster I might spike a higher peak temp but it will be for a shorter duration. Just because the i7 is the more Powerful processor doesn't mean it uses more Power.
If I'm playing a game at higher frame rates for 60 minutes, yes I use more power but I did more work. how does it look if we run both for 60 minutes at the same frame rate. games do something different in that they play and adapt using max resources over a period of time.
A spreadsheet calculation or another program though would do the same actual work but at different speeds. This might be via brute force or thru better efficiency. Its the Power in watts that translates to heat not the power of the processor.
I'm tempted to buy an i7 just to find out however, it would be largely pointless as you can't educate the Internet where all stupidity lives in equality with all scholarly work.

Too me this is the only practical differentiator between the two (spoken as someone who HAS NOT tried the i7). My opinion is based upon reading most everything here and at TabletPCReview - there just is not a significant performance delta to the i7 as configured in the Surface Pro 3. IF you need/want 512GB, then it is the only choice, but otherwise, I just don't see the advantage of the i7 over i5 in the sweet spot - 8GB ram and 256GB SSD.

Greyfox your post makes entirely too much sense...
