I fully agree about raising good bugs. It is a tremendous accomplishment to build a browser that works as well as the Micob. However I am sure you will agree that any serious discussion must be based on facts and it is a fact that Opera works sometimes better on the N800.
As mentioned before Opera lacks AJAX and that (probably) makes working in het Google environment slow and sometimes simply not possible. Here, MicroB is much nicer. It is also a fact that Google docs does not work with Opera and does with Microb - but still too slow.
I noted [...] that you are a very strong Mozilla / Firefox advocate.
