I'm surprised to find that Adobe has actually created a version of Acrobat Reader that doesn't suck. Yes you read that right: It doesn't suck. It's speedy loading up documents as quickly as FoxItReader. Another new feature is that you can select text in a PDF without clicking a button to do so first. Welcome to 2007 Adobe glad you could join the rest of us :) Also the UI has been revamped removing the ridiculous Yahoo toolbar and generally making for a much nicer and clean experience.
They're still trying to bundle all sorts of crap with the product when you download it but I'd still give it a whirl now that they're to par with third party products.
