Been using SP3 for 10 days now. Been a wonderful experience.
Pros
1. No curved screen
2. No overheating issue
3. Battery life aint too bad even during intensive activities, charges back up fast
4. No problem using on lap
5. 1TB oneDrive with Office 365 is much appreciated. Ditched my sugarsync.
Cons:
1. Hate the pen holder sticker, it is a sticker and will keep peeling off
2. Gets a little hot if used extensively
3. Metro Apps like media player are not really touch friendly, need more tactile friendly apps in tablet mode.
4. For my fingers the mousepad button feels a little flimsy and sometimes acts erratically.
Wishlist:
1. More than 1 USB port
2. A pen latch at a corner like a magnet to latch pen
3. More than 1 MicroSD card slot
4. Dock sold cheaper perhaps
