This is a tremendous upgrade, and this review adds some clarity that offsets many of the "meh" complaints made when the device was first announced.<p>It's really an underclocked Snapdragon 600 (Krait 300 cores). Screen quality is excellent. Cameras are decent. Storage issue is fixed (via fsTrim). DDR3 1600 RAM. Display is excellent (the brightness/contrast numbers are outstanding). 5Ghz 802.11n.<p>This is a <i>huge</i> upgrade.
