The advantage of the report_webkit for many of us is that the guys from
camptocamp (and others) have written fabulous reports for us it. Our
customers (and we) have invested a lot of money and time in a complete
suite of reports that we can throw away.

It will stop some customers from doing migrations, because the migration of
the custom reports will be too expensive. It's can be a real showstopper in
a lot of cases.

IMHO the official openerp reports are not always so neat and clean. (I'm
talking functional now, not techical) and in the 'real world'  users are
used to them and don't want to change for the official reports.

I think Niels puts it very clear in his mail :

"We should be able to do something smarter with the current landscape than
just throwing out working modules especially since every reporting engine
so far each has it's own set of missing features."

As Nicolas puts in his mail, what about maintenance contracts (v6.1 - 7.0
...)

And of course we will start to use Qweb reports and if it's better than the
report_webkit we'll be very happy and write all our "future" reports with
it.

Peter

PS : I realy like the things in v8 I've seen until now.
