What it seems like you are talking about wouldn't have anything to do with rooting really. It's just the software, and it will get updated. BTW, the Droid Eris isn't always smooth either. It lags on scrolling and screen transitions, at least the one I played with at the verizon store did.

BTW, Rachael or the SE X10 UI also turned out laggy. But then, the phone itself was laggy, so can't quite say its the UI. But it still has time to get worked out before its released.

 

I wouldn't use the one you played with at the store as an example. The Moto Droids and Droid Eris' I played with at the store were all slow and choppy. I think they must have been used by 9000 12 year olds. My Moto Droid and my wifes Eris are both smooth as can be and fast. They don't even compare to the store demo models......they are sooooo much nicer.

 

When I played with the store's Droid it wasn't bad. I also went ahead and closed any excessive browser windows as well as Advanced Task Killed every app.

I didn't have such luck with the Blackberry Storm 2, however, because the damned charging cable got bent so it kept replacing the screen with the clock (which happens when it gets plugged into a charger) every few seconds.

 

Hey guys,

I just traded my Eris (which I had for two weeks) in Saturday for a Moto Droid and it is night and day.

I liked the look of the sense UI but I had to constantly use an app killer to shut down apps to keep the UI snappy. Some of the apps start automatically even if you have them shut down (stock mail program, messaging) even if you arent using them. I think it is a software issue which causes the batter to drain so fast.

The Moto is soooo much faster with everything. Web pages load 3x faster. Changing the screen from portrait to landscape was close to a 2 second lag....Moto does it instantly.

I am sure it has to do with the hardware as well as the software.

I did like the look of the Sense UI but prefer the performance of the Moto.

The battery life is amazing on the Moto...used it all day Saturday since it came out of the box and battery was at 80% at 11:00 at night.

Just my opinion of the UI since I have used them both.

 

This is something I'm kinda hoping for also. I hope they can get a balance of a nice smooth UI experience without the lag of the Sense UI. Stock android right imo is more functional rather than providing a nice UI atm.
