I have Joiku and find it works 95% of the time. But that 5% failure means my family roll their eyes when I promise them an internet connection via my n900.

To be fair to Joiku the family views the N900 as a bit of a joke. I am considered the long suffering early adopter with my unreliable phone. My wife's Nexus One and daughter's Blackbury are viewed as the serious phones.

This reputation means that any interruption in service when using Joiku annoys the family instantly and they give up.

Would I buy Joiku again? Probably.

Would I recommend it to others? Not really.

Same answers I would give if you asked about the N900 itself.
