Pros:

1. I find the KB very responsive on my Treo 750. I loaded it to get used to on screen kb input in preparation for my Touch Cruise.

2. The calculator function is very cool and is helpful for spreadsheet entry when in a single cell.

3. The iSkin is nice and "spacey" with enough space between the keys to make it comfortable.

Cons/wishes:

1. Needs a better way or at least a documented way of changing the kb. There are plenty of config and map files just no real documentation on how to manipulate keys.

2. Need a way to be able to press-and-hold a key to generate another key. For example, I want to be enter a "_" (underscore) by press and holding the "-" dash key.

3. Would be nice if you could resize the KB on the fly ala TouchPal.
