Welcome and I'm not sure what your looking for in the Instinct HD, but maybe I can help clear up a couple things for you.
Calander - set up your gmail cal from a computer and have it set to alert to your phone. The gmail cal also has daily, weekly, or monthly view and all your upcoming event will be displayed ahead of time ( set your main menu up in a list view like the favorites section is set up )
Texting...takes some getting used to, for better results flip your phone to landscape view ( on it's side )
gets easier with time, as with any phone.
This phone will lag for a bit whenever exiting the web, but it doesn't last long.
Camera...Video recording...hdmi out for movies on a hdtv...3 of my favorite things
