http://forum.xda-developers.com – What can we stock users expect from a custom rom like cleanrom? Is it really that much faster? Will the input lag be solved ? Because now my tablet takes a few seconds to catch up with what i wrote. I get a lot freezes where applications hang. Especially the stock browser, every few minutes i get "program is not responding" wait or close Overal the tablet feels laggy and slow and i wonder if cleanrom will fix all these issues or that i have to accept it as it is (HowTos)
