Jelly Bean features include Google Now, smooth UI called Project Butter etc. If you are one of the people who got Ice Cream Sandwich update, you must be seeing slowness when using your android phone. I have Samsung Galaxy S2. I got Ice Cream Sandwich update couple of months ago. Swiping is not smooth on ICS on my phone. Nexus 7 with Jelly Bean OS feels good.
