My HP replaced a 6 year old Dell that was underpowered by today's standards and whose reaction time had slowed to a snail's pace despite everything I could do to clean it up and get rid of superfluous software, etc. I decided to get the solid state hard drive in the HP for speedy data exchange and guess what? It works. The core I-7 and 8 gb of memory help, too, I suppose. One phenomenon I notice is that, while it took only 9 seconds to fire up or shut down at first, it now takes more like 20 seconds. All I have really done is activate the full version of Office Home & Office. I have this suspicion that every Windows or HP update starts to slow things down, and am tempted to refuse as many updates as I think I can get away with. Regardless, the old computer took 10-15 minutes to start up or shut down, so I am happy with the improvement. And every operation is virtually instantaneous. One point to consider: to wake the computer from sleep, I have to touch the start button on top of the computer. Since I have the box tucked into a shelf behind my desk, it's rather a long reach. I would prefer just jiggling the mouse to wake things up as my other computers do. Regardless, I am very happy with my new HP.
