I made an account just to provide some balance to the glowing reviews about the Surface Pros, and to see if I'm the only one here that feels this way. I own a Surface Pro 3. I want to like it but a few things ruined it for me.
TL;DR: Unless they redesign the charger and make the touchscreen resilient to cracks, I won't be buying another Surface in the future.
Complaint #1: Am I the only one here super frustrated by the design of the SP3's (and SP4's) charger? Specifically, the magsafe-like plug. It frays right where the cord meets the plastic plug and short-circuits. You can actually see the spark inside the plastic piece that connects to the computer, and the LED indicating it's connected to power will flicker on and off. I've owned two cables now (the original and the replacement I got for this issue) and it's happened on both. There's a thread here about this: http://www.surfaceforums.net/threads/power-cable-fraying.108...
The result is I have to be very careful when it's plugged in, because if I move and shift the cable, it might short-out and the computer shuts off (and it resets my Surface's time, too). Also, annoyingly, sometimes the LED in the plastic magsafe plug indicates it's connected to power, but when I connect it to the Surface the Surface says "plugged in, NOT charging" (emphasis mine).
Microsoft recalled the power cords due to the AC power plug, but not the magsafe connector. So when I contacted Microsoft about the recall, they sent me the part that plugs to the wall, which was not the problem. I've tried reinforcing the connection with electrical tape, and that helps to a very limited extent.
Complaint #2: A month into owning the SP3 I dropped it and the screen cracked. This broke the touch screen (the Surface thinks I'm repeatedly tapping where the screen is cracked.) I had to disable the touchscreen drivers to make the Surface usable, so now the tablet functionality is all gone, which is a bummer because I bought it in part for reading and videos. And, even with the drivers disabled, when the computer boots up from power off, it often waits indefinitely at the screen with the word "Surface" unless I "massage" the area where the screen is cracked. This behavior (and recommendation to massage the screen) is documented in this reddit thread: https://www.reddit.com/r/Surface/comments/4vmimv/surface_pro....
Dropping it was my mistake, but I wish the Surface's touchscreen was more resilient/better able to handle cracks. iPads and iPhones seem much better off in this respect.
Complaint #3: Occasionally, the Surface will turn itself back on when I've pressed the power button to turn it off. The result is I'll come back to use the Surface later and the battery will be totally dead. I'm 85% sure that it's not me hitting the power button to turn it back on, especially because my power settings are such that, if it's sitting idle for 5 minutes, it should go to sleep.
I really like the Surface in a lot of ways, but the issue with the power cable and the fragility of the touchscreen make me unlikely to buy another Surface, and make me hesitate about recommending a Surface to a friend.
