If you want a fast, resource-friendly pdf reader, you should look no further than the free Foxit Pdf Reader available here: http://www.foxitsoftware.com/pdf/rd_intro.php It is 1.5MB and even allows you to type directly onto pdf documents - useful for form filling esp is you have terrible handwriting. By contrast Adobe Acrobat Reader is a whopping 20.8MB download and AFAIK, it doesn't even allow you to type onto the pdf. It is slow, and too large for what it has to do. So avoid like the plague. Adobe Acrobat Reader is to Pdf Readers what Norton is to Anti-virus. Hope this helps.
