The latest dev version of Google Chrome performs (most) of these CSS3 transitions too. The one transition I didn't see was the "video in a round frame". Maybe it's my system, but I thought the text rendering in the first transition example was sharper in Google Chrome than in FF b2.
I can't seem to get the Bespin Bookmarklet to work with the text box in hacker news comments' text box. I tried the same thing over at reddit and same situation. I can type text in the box but the submit button doesn't respond nor do the drop down menus. Attempted with latest versions of chrome and firefox. Disabled NoScript as well.
Not if you love the act of programming. You will know when you've programmed for a couple of months. You can teach yourself but in the end you really have to enjoy the process of programming. Helps to find out which concentration in programming you are good at: databases, games, engineering, etc...
