For Performance (which was most important to me):
The processor clocked almost never to the maximum Turbo clock of 1.83GHz, but remains at 1.53 Ghz, regardless of whether 1 or 4 cores are used.
Very surprising is rather that even during video playback, the CPU only with 400-500 Mhz clock needs. Even if the processor is slow, the basic software for everyday (office, videos, surfing) is functioning properly and the service is fun.
The 1GB of memory is the weak point of the device, you should watch that you do not have too much open and always best to use Metro apps because Windows can act this well. If the memory is full, the unit begins to stutter.
The 32GB of memory are much more for the price. Normal 16 plus is the memory it quite fast. Dell sets default on encryption. If these safety is not important, it may disable and thus almost doubling the memory performance.
The facilities and processing:
It is not perfect, but may very well and much better than you'd expect from the price at all. Top!
Only a second USB port I would have liked.
The front camera has pleasantly surprised me, because it is better than the Surface Pro2. The main camera is approximately at the same level as the SP2.
For battery life I can not yet say reliable, but this seems to me very good as well.
I have already recommended this Tablet friends! Unbeatable price / performance ratio.
