I am interested in purchasing a Blackberry Playbook 7". The main use it will have will be for me to read PDFs posted online by my profs in university during lectures. Also if it is possible to read a 1000 page PDF clearly and without lag. Anyway if you are unsure maybe I can send a sample PDF that you can test out.
EDIT: also if it's not suitable what other tablet should I look into? Please not something that's going to cost a lot
