The Tab and Tab 2 models have always been a little notorious for slowing down if too many apps are running at once, but the Tab 2 fixes this by offering a button at the bottom of the screen which shows what apps are running and gives you a way to quickly close them out (without losing any work!). With that option in place, I have never had any problems with sluggishness on my Tab 2.
I will agree the camera is horrible, and for me I have a tablet and i did not get this because it did not have the inputs that i wanted (i like to have a usb, sd card, and camera, if those do not have all I will not buy it
