HP's all-in-one systems come is a variety of different models but most carry the ENVY name now that was one reserved for their premium performance systems. While there are 27-inch non-touch models from HP, the 23-inch model is as high as their TouchSmart models go to but they still do try and offer higher performance than their more entry 20-inch version. The company once reigned in the touchscreen all-in-ones thanks to their custom software but it doesn't have that same edge now with Windows 8. Does their new performance touchscreen still have something to differentiate itself from their growing competition? Find out in my review of the HP ENVY 23-d055 TouchSmart all-in-one desktop.
