Useful apps for desire that are unavailable on lower spec handsets

[Shazz]

Hi everone, through researching the pros and cons of the htc desire and wildfire, I've seen one of the negatives of the wildfire is that some apps are unavailable that are available on the desire. This may be the deal breaker for me but thought I'd check what some of these apps are. Ifvthey are some obscure pointless apps it doesn't faze me, but I mean the really cool or useful apps, if they are unavailable I'll definitely be opting for the desire, could anyone give me some examples please thanks very much!
