Google Docs now has a PDF viewer

As ubiquitous as Acrobat Reader is, it's clunky, and I often wish there was a dedicated PDF viewer as part of Google Docs. Well, now there is! You can simply upload PDF files to your Google Docs to take advantage of this new feature.

After opening one of your uploaded PDF files, you are taken to a new PDF viewer that lets you search , see a preview of each page, and copy/paste text -- Basically the only three features I care about.

It's strange that they decided to re-invent the wheel here though. Google Book Search and Google Patent Search are great examples of a technology that would work very well for viewing PDF documents -- compared to these two, the feature that's currently in Google Docs feels very beta.

What do you think about the new feature?
