Well it's running on a mono webserver on-device and first load of page takes around 45 seconds to 'just-in-time' (JIT) compile it the first time that page is served up. But in theory you could start up the webserver either automatically or a menu icon could be created to launch server... then you'd just have an internet shortcut to use editor.

Kinda bulky but yes usable... its fairly responsive. Some features have maybe 1 second lags but it can keep up with typing and navigation just fine.

One of the cooler aspects is that you can browse your device from a desktop, and edit/save existing html from and to the device. So you could edit the html from desktop, click save and it will save to maemo... click 'save as' and it will download just the html to your desktop... click preview and you can view the html as a web page and print from desktop.

Probably more worth it once several web features can be included... to give you kind of your own portal

The best part about asp.net is that it targets the web which is probably the most common 'widget set' out there (as opposed to gtk or winforms or osx).
