I did my two weeks almost on the i7/256G SP3 before returning it to Microsoft. I loved it. The i7 was amazingly fast in comparison to my i5/8G/256G SP2. A Norton scan would complete in 52 seconds rather than 2 minutes, web pages would load in 1/3 the time. The trackpad was good enough I didn't need my Arc Mouse Surface Edition and the extra screen real estate was welcome. What was missing was the Wacom EMR layer and the passive pen. The new Active pen technology is a pain in the arse with the major problem palm rejection or lack of it. I just replied to a new thread on the same subject with a new SP3 user complaining of this. Yes, I tried full screen. I also didn't enjoy actually handwriting as much on the SP3. You may think it unreasonable but I write notes several times a day at least and I'm using it more and more every day. I had the SP2 for about three weeks, having bought it second hand before buying the SP3. Yes, it is squat, ugly, the finish is crap and it scratches easily but it all works! The pen also attaches magnetically into the recharging slot, as you know and it feels therefore that the pen belongs. I am just so glad I didn't sell the SP2. Honestly though many Surface users don't use the handwriting part of it. If so then I can't recommend the SP3 enough! I had no heat or other issues.
