I suggest you take a look at the Treo Pro.
Although Turbo may have had a different experience than myself, I can state that as far as responsiveness and reliability of the device, the Treo Pro wins hands down over the Touch Pro even with the limited RAM.
I have a Touch Pro 2 Treo Pros. The Touch Pro is my all-day device, while the treo is my secondary. I love my Touch Pro, but really really like my Treo. Give it a shot, I think you'll like it.
