The iPhone is by far the 'best' phone I've had...and it syncs with my iMac really well.
I'm going to get the £159 16GB version since I'm on the 35quid/month plan - especially since I will have to shell out for the next iPhone..might as well enjoy the extra space for more photos, music and applications
I use Macs, since I'm happy with them...but I wouldn't call myself a 'fan boy' per say...but YMMV. I just find the iPhone a darn good phone - it's so much better than Sony's OS, or even UIQ.
