Poorly written, not sufficiently tested, unoptimized code ? It seems strange however that after having developed Internet Tablet for 5 years, the worlds biggest mobile phone company, can't write a browser, that performs decently on the most capable hardware they've ever shipped. The fact that it works fine for others, provides some relief though, as hopefully this can be ironed out, in future iterations of the firmware. Then this'll be a leading device on the market. I just hope Nokia are aware of this, and are working to get there.
