One little thing I miss on my Blackberry was that I had it set to vibrate once for Social Network notifications, twice for an email and three times for an SMS. That way I knew how important it might be and whether to take it out of my pocket. My T-Mobile G2/HTC Hero (1.5) doesn't SEEM to have the option to change the default "vibrate twice". Is there any way of changing it? Or an app that might do it?
