Yeah I agree Qt is a relatively large download for a platform which doesn't have it as standard, but only if you don't use any other Qt applications. However, using the Qt for this project was more of a refresher course for me and it does open up a lot more applications for use on the Tablets.

Also, after reading the pdf presentation (page 5) on Maemo 5, I believe Qt 4.5 will be included - which will mean no additional downloads for users on Maemo 5. Including Qt was to be expected tbh as Nokia now owns Qt
