Normally when there are sequels of phones, the sequel usually has some much improved features however with the HTC Evo 4G Shift it almost appears as if the phone has been slightly downgraded. The HTC Evo 4G Shift does have a full QWERTY keyboard however the processor power of the Evo 4G Shift does seem to be a step down from the regular Evo. The HTC Evo has a 1GHZ processor which seems to be becoming more and more standard with smartphones however the Evo 4G Shift has an 800MHZ processor. Although this is the same processor power as the T-Mobile G2 which is enough to get the job done however when it comes down to it when you make a sequel of a phone it should be better than the original.
