Written using Nokia 770 with OS2008he installed. This includes the Firefox-based browser which, while far better than the previous Opera-based browser has a really annoying behaviour when you use the backspace key. Not very satisfactory really, but better than nothing. This behaviour doesn’t appear when using the thumboard, fortunately. However, when using the normal onscreen keyboard the keyboard disappears everytime the you move the caret. I would expect that an external keyboard would work fine.
Seems this is only an issue when editing insalled fullscreen mode.
The main advantage in this browser, is that the full formatting toolbars are accessible.
