Exactly that. It's an equation and both sides are important.

Criticise, pick holes, find room for improvement, write about the negatives.

But also work with people who are able to make those improvements. Build the community, be part of the community, help make it a better device.

When something that used to suck is made better, perhaps helped on by criticisms, hole-picking and public writings - make a point of writing about those improvements. Make a point of writing when something used to suck - especially something you publically criticised - and how it was made better.

Not now, not yet, because it's just been released.

Just make a note to remember what you didn't like now, and check back on those things in a few months - make a note to write about changes. Drive the developers - inside Nokia and outside - in the right direction with your criticisms, but don't forget praise in the right doses too. It works wonders. Complete the equation. Be happy. Make the world a better place
