In one word Cumbersome.
Just because all the apps that I wanted are available and I had to download all and setup

otherwise it was awesome experience with the switch. (So far... lol) Now I think like every second user I have to start asking when will I get the update

When in India

hardware cost me 130US and performs heaps better than the 1020 which cost me an arm and a leg... well half a leg.
first 1020 I had to return due to hardware issues and second one is still running, but apps started vanishing as there is no WM10 for "all devices" after all.
firs droid was returned due to faulty human not deciding to check the network bands that are available on the phone and its compatibility in the country of use but the subsequent one that came in fixed the problem and the back restore on it was pretty much seamless.
Few features from WM, I miss, but pretty much getting over it as we speak and I don't think I will go back to WM10 unless something major changes *cough* app gap *cough* and cost to buy outright phones like you have with android.
Looking forward to Nougat and its split screen options and improved usability with shortcuts and tweaks.
Cheers
