I need a tablet pc for work. I don't need anything fancy, in fact all I really need it to do is display word and pdf documents that open in a browser. It doesn't need all the internet bells and whistles. An ethernet port is really all. I saw some HP's selling on Amazon for around $150 and thought that couldn't be right. The $ does appeal to me since spending the $ on an ipad is overkill. Any recommendations on a price conscious tablet?
