Bought a 7520 and am keeping it on 16.04. could not be happier. Highlights: 32 GiB of RAM 15" 1920x1080 FHD matte screen with no mic or webcam 1TB storage Xeon processor (equivalent to top end Mac processor) So... Many... Ports Battery life with screen I picked is amazing Ability to fully customize the beast Painless Linux experience (truly). Down sides: Heavier than a MBP A teeny bit of coil whine Charger is 180W....and big too Cost -- as much as a rMBP, but for the dollars the hardware is dramatically better in the areas I care about. Go spec it out if serious and make own decision though :) I love this computer. I know some people may consider the 1920x1080 15" screen not as nice as Retina (you can get a Retina density display on the 7520 if you want), but I find 144ppi perfect for 15". Better than anything of yesteryear. Also I was able to get /exactly/ what I wanted at each option for a reasonable price and no compromises. Anyhow I can finally tell people this is a good idea if you are comfortable on Linux.

I just got the same... notice that besides the 1TB SSD you can put inside an additional 4TB HDD. the only problem is that turboboost does not seem to work out of the box, is it working for yours?

  You know..... I haven't checked. I only kicked the tires on the discrete GPU. I have been looking at this now. It seems, according to `turbostat` that one core reaches 3000mhz (indicating turbo is not kicking in), but... see below: I have https://ark.intel.com/products/97463/Intel-Xeon-Processor-E3-1505M-v6-8M-Cache-3_00-GHz https://ark.intel.com/products/97463/Intel-Xeon-Processor-E3... so Turbo should hit 4ghz I tried this: https://askubuntu.com/questions/871308/enabling-disabling-turbo-boost-16-04 https://askubuntu.com/questions/871308/enabling-disabling-tu... and put a 1 in /sys/devices/system/cpu/intel_pstate/no_turbo and it dropped the cpu frequency from ~2700 to 2200 according to the `turbostate` command. However, when I run i7z it reports a frequency of 3000 (maximum frequency without turbo), which is correct, and a frequency of ~3600 mhz (freq multiplier of 36x, which is one of a possible 40x, 38x, 37x, and 36x turbo multipliers) so I /think/ it is doing the right thing. I am going to assume turbostate is not correctly reporting the frequency using the correct multiplier, but that may not be true. It is definitely scaling the CPU speed. And, anecdotally, it compiles things very quickly :) What sort of investigations have you performed?

I purchased my Precision 7510 almost 2 years ago and it has been a great experience with almost every Linux distribution I tried. Battery life (with a few tricks) is almost 9 hours and performance are astonishing. The only downsides are the weight and the keyboard... for those reasons I recently tried and bought a Thinkpad T470 but I am now really missing the P7510 power and speed

  Keyboard in the 7520 seems pretty solid. An improvement over current generation Apple keyboards and... solid feeling. I wonder how different 7510 is over the others. This one is not my beloved mechanical keyboards, but it does not fatigue my hands at all, and has a full numpad :)
