I got a new Samsung Saga a couple of weeks ago and thought I would share my experience with it so far.
It runs Windows Mobile 6.1 Professional, has the ARM11 MSM7500 processor, and 85MB of RAM.
My unit came with Opera and IE on it, but I usually find myself using IE. Web browsing is pretty consistent with my past experiences using mobile devices.
The screen is a little hard to see in direct sunlight, but when not in direct sunlight the display is easy to see and read from.
Setting up access to Exchange was a breeze since it just connects through Outlook Web Access (OWA).
Battery life seems good, I used it over the weekend, fairly heavy on Saturday, without needing to plug it in.
I still have a lot to test and play with, but so far I am having a good experience with this unit.
