Moving from Mogul to either 800w or Touch

[nization]

My dilemma: I have the Sprint Mogul and it's fine and all...except the awful lack of memory. So I am looking at either the Touch or the Treo 800w.

I understand the Touch is great and better than the Mogul in every way with the exception of it's lack of physical keyboard. I'm sure I could get used to this and live with it...but then I looked at the Treo 800w.

The Treo is nice for the keyboard, even if it is awkward compared to the Mogul's keyboard. Again, I'm sure I can get used to it however. This one's first fall back to me seems to be the smaller screen though.

Does anyone here have any suggestions one way or the other? One big thing is that I do like to be able to play with third party apps and such. GPS access is a must (I believe these two are fine in that area) and tethering without the PAM plan is wonderful.

Thanks
