A lot of people complain that the BlackBerry PlayBook doesn't have a native app for email.
I don't complain about it because I rarely use email, a couple of emails a year from non microsoft sources is about it.
I did get an email from my brother the other day saying that there was a problem with his computer. I emailed a suggestion that he should reboot the computer. I went downstairs later to check and see if that had fixed the problem.
