I've just stumbled over this on the Wizards web site: :Players Basic Rules the same text as the PDF download but all nicely presented as HTML pages with clickable indexes. I didn't know it was there. Did I miss an announcement? Has it always been there or has it just appeared?
It might be new. It's hard to tell.
Wow. Nice find and I had no idea.
Apparently it is new - announced a few hours after it went up and also reported on ENWorld. It's a nice format and apparently works well on mobiles.
This is awesome. I just found it too. Now I can access these on my tablet with ease.
It's possible to download the whole bundle using File Save As .. in your bowser and read it offline later. This might be useful if, for example, you are going to be playing in a hall with no wifi.
