Iphone 4 facetime.. Its a game changer..

So I was having conversation with one of my friend who has bought this all new
shiny iphone 4 with facetime. So the conversation went like this.

me : So, what is so special about facetime when I can use skype to skype video
chat?
iphone owner: Dude it is HD, the picture is crystal clear and look how easy it to call.
(He demoed a call to another iphone 4 user, picture too me was at par with skype).
me: Picture looks as I see in skype, I do not see any difference.
iphone owner : Because the light is low at the other end. But it is HD, it changes the game again.
me (thinking) thats how it is with any other camera.
me : So, why should I buy a iphone for doing video chat. Anyway it does not
support video chat with other people who do not have iphone 4.
iphone owner : skype is outdated technology, this is a game changer your call goes through 3g while video through wireless.
me (thinking) so, if it is going through wireless, then why not send the voice through wireless and do video chat?
iphone owner : skype should have innovated and brought this "game changer" technology.
me (thinking) skype video/chat works on 3g phones with data connection.

Anyway I didnt trouble my friend so much that time as I didnt have much data with me. So, I check out the resolution of the front camera on iphone. It is 640 x 480. Now, on a small form factor like a mobile phone this would look HD any day. Even other comparable phones sport the same resolution of 640 x 480 in most cases. May be apple has added some special ingredient which is upconverting 640 x 480 to 720p or true 1080p hd :-)

And then again I remind my self that "dude it is the game changer again".. :-)

Also, one more thing I have learnt is that it is better not to argue with iphone zealots as they cannot/would not take data points in favour of other phones, they just use iphone "data points" to show their alleged supremacy but would not digest others data point...

Disclaimer: I know I have lot of friends who have iphone, so please do not take it personally
