one thing that now works for me that never did before is that the file manager now lists windows and SMB servers on the lan, which has been a bonus.

also, file manager shows bluetooth devices like my phone, again, it never showed that before.

it does seem slower connecting to wifi.

I've not exercised it enough to comment on speed of the browser.

EDIT: yes, its definitely a bit "snappier". was browser Auntie Beeb's news this morning and pages rendered faster with zoom and full screen switching being very quick - it nearly completed the zooming before the pop-up appeared saying "zoom to 120%". Thanks, Nokia.
