New Version of Acrobat Reader
I don't particularly like PDF documents, but that's how most eBooks are distributed. Since I do a fair bit of book reading on my laptop, it's noteworthy that Acrobat Reader 6.0 was released yesterday with significantly improved "CoolType" - Adobe's answer to Microsoft ClearType.
You have to enable and tweak it thru "Edit"->"Preferences"->"Smoothing".
While I'm at it, here's an Acrobat quick tip:
To disable the annoying loading splash screen, go to the "Preferences" menu, select "Startup" and de-select "Display Splash screen".
Update: I just realized that the space bar finally moves to the next page too!
