Thanks to all for your comments. I guess I am officially part of the Android Central Community now that I have an Android device.
So I got it last night and have been playing around with it. So far so good. LOVE the voice activated functions--though I would not have known about them if my brother had not showed it to me on his Droid.
A few observations:
Hate the contacts app. Why won't it let me sort by last name? Also, what happened to my categories/groups?
Love the availability of most of my favorite Treo apps AND most of the really cool iPhone apps.
Love the multitasking/quick switching.
Trackball usefulness not clear yet--still trying it out.
Love the haptic feedback.
Getting used to the keyboard.
Waiting for a better calendar app to appear.
Will need lots of advice & recommendations about favorite apps, etc. (I will make a separate post about this--after searching

)
Probably gonna get the nutshell case--had one for my treo and it is really the best out there. Debating the sedio two-piece skin case (forgot name) that I have on there now. Like the extra protection, but it seems that I would not be able to use a cradle with it on. Plus changing batteries will be a pain.
BTW, removable battery is a huge plus. I loved this about the Treo--if you are on the go for a long day and can't plug in, you can still keep going.
So . . . those are my initial impressions.
And yes, I am having fun with my new phone--especially coming from the 2.5G Treo 680!
Cheers,
