At 11:30pm, I finally got ebook applications v1.9.0.3 to load onto my PRS-300.
At 11:32pm, I hit "Back" on my browser and found out that they just released v.1.10.0.4 which includes applications like Sudoku, Chess, Calculator and other stuff. Not being one to rest on my laurels, I downloaded the zip file to update 2 minute old software.
After a failed first attempt, I got it to load at 12:20am. Now I'm going to load some books and play with it for a few minutes before I go to bed.
Yes!
