The tablet is so light (for a full core i7 PC, 800 grams for tablet alone) and typing on the type cover is terrific as the keys are quite broad. The 3:2 form factor actually makes the tablet very usable compared to the longish 16:9 in many laptop and tablets. Kudos for Microsoft for daring to be different. The ability to do work in a Portrait orientation makes me so ultra productive as I can see my entire page all at once (very important to me). There are so many pluses in Portrait orientation, I can read an entire webpage at one go without having to zoom in. However, there is a caveat. When in portrait orientation, you have to unplug the type cover and essentially the type cover is useless when it is not plugged into the SP3. So you have to get an external (preferably bluetooth) keyboard for that. It sucks that it has only 1 USB port and despite what I have read online, the battery life was so-so for me....around 5 hours plus. Maybe its because I am using the core i7/512GB version. I would have gladly accepted another 100g of weight on the product in exchange for slightly longer battery life.
I think the sweet spot for this product in terms of price/performance/battery-life is really the core i5/256GB version. Occasionally it does get pretty hot at the back.....I am not sure if it is because of the core i7. Also, I used to own a Lenovo Yoga 2 pro...and although I like that laptop, however, 2 negatives for me...the yellow colors are more like mustard and there is no way to overcome it and Lenovo is pretty much ignoring the issue....and the standard SD card slot has 80% of the SD card sticking out of the slot. The screen and colors on the SP3 are very accurate and the 2K (2156x1440) resolution is sharp and bright. And Microsoft hid a micro-SD card slot behind the tablet hidden by the kick-stand and its terrific. However, the micro-SD card tends to go to sleep very often and the only way to wake it is to pull it out of the slot and push it back in. I have found no way to get the micro-SD card to stop going to sleep. The accuracy of the PEN when taking notes is very very good compared to many tablets that I have tried before and its smart integration to One Note (free) and One Note 2013 (free also I think) is fantastic.
