Totally new to tablets as well as android. All I need is a PDF reader in a device. No webcam or anything else really, just the ability to read PDF and do some basic web browsing. No youtube or email or anything like that. It's mostly going to be used to pull up reference manuals and study guides. Looking for something that's very cost effective but isn't a total POS if you catch my drift. I've looked at the zenethink as the size would lend itself well to manual PDF files but i've read mixed things. I would prefer to set my budget limit in the $200 range if at all possible. Thanks for your help.
