More apps mean more variety, most of the time when I need to perform soemthing, i will just search in the appstore and download it.

If I wan a guitar tuner on the spot, I just download it.
If I wan to a thesaurus, i just download it.

I get to do what I want on the spot, which is not available on other platform.

FYI, I owned both IOS and Android devices. I can say Android market is full of craps, without proper control, not to mention not all apps are suitable for each android devices(Google framentation on Android platform - imagine having diff Android manufacturers, diff screen size, diff hardware, diff OS, you cant expect the developer to cater for all the androids phone.). Some of the apps even have spyware inside, or does not perform what it claims.

IOS is diff, you will get a surprise everyday. within last few months, there's something known as Tango - Free video calls over internet/3g, then last month got Viber - Free VOIP call. I can see from my contact list more and more people using IPhone, as those software will be able to detect who is using those apps, then ios user can call/video/msg them directly - FOR FREE ! Browsing the AppStore has become a habit, checking for the Top Free apps, of coz one can always browse the Top Gross - mostly some nice games such as Street Fighter, Hot Pursuit 2010, Mortal Kombat and such...These are the apps wont be available on Android(Maybe later, by that time IOS already has 2nd or third version), take Angry bird for example.

I am not an Apple Fan boy, i've been using PDA since Windows CE, then Android, then IOS, i used to hate Apple as their hardware is always inferior compare to others(HTC, Samsung), however, after getting my hands on Apple, I realised that a GREAT hardware without good apps is like a magazine with a good Cover but no contents.
