So I was recently on a two week family holiday and usedmy 1020 as my main camera (both for photos and video) and took over 2000photos.
Here are some issues I run into.
1. Copying Photos
First off I had to move over 30gb of photos and videos over to my Surface Pro, over 3 copy sessions during the holiday (about 10gbeach time, as I did not want to run completely out of space on my phone) whichof itself would not be a big issue, but the copying was painfully slow eachtime taking well over an hour and needing me to plug in my Surface on two of thoseoccasions.
The Surface Pro has a great fast USB 3.0 port butcombined with the very slow USB 2.0 on the Lumia 1020 and the large amount offiles being copied and you start tearing you hair out as to why Nokia did notput in a microUSB 3.0 on the phone (even if for full support you had to waitfor WP8.1 update?).
2. Nokia Camera Apps
Second big issue I run into is with the great NokiaCamera apps, i.e. the Pro Cam App and the Smart Cam App.
Both these apps have a serious flaw; that being theirinability to save edited photos to the camera roll. i.e. in the Pro Cam App youcan’t save multiple zoom ins from the same photo as it always overwrites theoriginal 5mp image.
The Smart Cam App has the same problem always overwritingthe original photo without the ability to save the new ‘version’ to the cameraroll. You are only able to email/upload/share the new edited photos, but unableto save multiple versions to the camera roll.
This is a serious deficiency in both these apps and makesthese great features useless when you don’t have a data connection to upload oremail yourself the edited images.
3. Now on a positive note. (Camera Grip)
The Nokia camera grip is the best accessory you can buyfor the 1020. During the two weeks (part of which were camping nights) it nevercame off and added valuable shooting time without which the phone would be deadby lunch on some days.
I still occasionally had to plug the phone into a carcharger during a heavy photo/video days, but on most days it lasted into theevening.
The grip is also invaluable when it comes to one handshooting or just for holding the phone in one hand while walking between siteson a trail or in the city.
Since I came back the grip is still on my 1020 and itwill probably stay on, apart from the added battery it provides a great tablestand and with the Nokia Glance Screen serves as a nice desk clock when at homeor work.
That is it. I could go into the great photo and surprisinglybrilliant video quality the 1020 has, but that has been covered to deathalready and this post has been long enough.

.. I don't know what your tolerance is, but on my pc I get around 10MBps copy speed from my device. So going by your 10GB it should take 15 minutes. I wouldn't tear my hair out, instead just play a small game until the copying is done for that. Maybe it is a localized issue with your surface pro and 1020.
