Just like the rest of the 'APEX World' I immediately jumped on the 4.0-bandwagon and signed up for a workspace on http://tryapexnow.com . Although I have seen a lot of the 4.0 stuff this year, but having the thing in your own hands is something completely different! IMHO this version (even without Websheets!) is the major APEX release ever. There are so many new, enhanced or restyled features, it just blows you away on first sight. I almost feel a newbie again... I hope to find the time to dive into some new features the next couple of days (or probably weeks..).
