The Mogul's scroll wheel was the best. Very useful to scroll pages and press it in to select. The Touch Pro's D pad was good as well, not quite as good as the scroll wheel, but it worked. The Touch Pro 2 takes a little getting use to, but once you do its sooooo much worth it. It's such a superior device compared to the TP1 its not even funny.
Luckily I have big enough hands where I can work it one handed.
