I have the standard applications – Settings, App Sore, Clock and Maps.

The downloaded apps I have are:

Sky Mobile TV – Watch the footy wherever I can get a wifi connection.
Sky+ App – Incase I forget to record something.
Sky Sports App, checking live footy scores on the go
Drop Box – Access to files on the go
VNC – Access to my Mac Mini home server when the missus is watching eastenders!
Air Mouse – Used as a wireless mouse for the mac mini (hooked up to the HDTV)
Apple Remote – Pickin a song from anywhere in the house.
Skype – speaking to the parents in Australia.
Ping – pinging the parents in Australia
Mail – checking my Gmail
Facebook and Twitterific – for the socialite in me

On my fixed bar I have the Phone, Messages, Safari and Ipod apps as I use these the most.

I think my home screen covers my three passions in life – Sport, My Mac and my family/social life.
