I have had nexus 7 for quite sometime now, like how smoothly it runs. I mainly bought it to read PDFs and some light browsing. The screen resolution is so good that I have not touched my reader after getting this tablet. Will keep using it and will write more later.
About the bad now. I have found that the quad core processor shows a bit of lag sometimes, especially while accessing the play store. Some games also lag a little but I not much into games so no complaint.
