From my experience i can tell you to NOT upgrade.....I have a Venue 11 Pro. If you use your gyroscope sensor for apps. Dell, as you can see from your tablet's driver page has NOT released drivers for the devices. Probably they think that ppl use laptops and dont need drivers because windows 10 has them. Well....at least fgor the gyroscope sensor it doesnt. So if you like to use apps like point to sky or watch youtube 360 videos you cant.
I find it unbelievable that Dell.....one of the closes Mirosoft partners got caught unprepared like this.
Beside that......because there are NO drivers provided by Dell....the camera will NOT work.
I used to use the gyro sensor a lot and if the drivers don't come soon i will have to return to win8.
Please fix the problem Dell, I dont want to regret not buying from someone that fully supports win 10 and doesnt rely on the fact that Windows 10 has the drivers integrated.....because for this problems it DOESNT.
