Very nice! Will need something slightly more subtle though but you are really getting there! (And this looks too much like our competitor Yobongo)
If you think Google (prime colours to show cheekiness), Apple (simple classy apple), Fedex (an arrow between the letter "E" and "X" to give the impression of moving forward, fast), etc.
What we need really is a Favicon together with the design of the words (think Belugapods.com, Yobongo, etc) - something easy to relate too.
