Android phones, apps and tablets

What's wrong with Gmail? I only use the gmail app. I had work emails on the phone once with the HTC email client but couldn't be arsed living and breathing work 24hrs. Killed it off. Gmail does what I want but I'm using gmail on PCs most of the day anyway so I don't use it 'that' much.

I was using the HTC client to read my googlemail account. I like the way you can set it to sync at different times on peak and off peak etc. can't see any of the sync setting for the gmail app, unless I'm just being dumb. how often does it sync?
