I've been using it for more than a month and currently luv it so much.
Luv the design, the user interface, the slim form factor, the safari browser, the 2 MB camera, the ipod, the accelerometter, cached google maps, the shell, ssh & sftp, and many 3rd party applications..

It sync easily with outlook through iTunes. Though I have trouble installing iTunes on one of my PC, but I use my laptop anyway to sync.

It's connectivity is not as expected though, with no 3G, bluetooth does not work, can't send contacts or pics or songs via bluetooth. It lacks of GPS receiver also.

But still, everyone amazed with my iPhone, so I luv it. ^^

Maybe I will still in luv with it until SE X1 released. Let's just see.
