I ordered the 12GB ram, 512GB SSD variant and am very pleased with the performance. It handles instances of Origin, Mathematica, and Matlab simultaneously running without bogging down. Large files load very rapidly.Extra bonuses: Fast bootup and shutdown (generally ~4 seconds startup from a full shutdown, even faster from sleep mode). Windows updates have been under 30 seconds. On my *old* computer, this would run the disk at high% and last much longer.Do note that the GPU is extremely limited and the despite the computer being a workhorse, it struggles to render high quality 3D graphics. If you intend to game with this computer, a GPU change will be required.
