iPhone - 3G - worth it?

I recently pampered myself and bought the iPhone-3G. Prior to this, I owned a basic Nokia cell phone; so needless to say this was a big bump in features.

I love the iPhone for following reasons

1. The user interface is very friendly, intuitive and easy to use.
   
2. Key applications organized at the touch of a finger make it easy to get what you need rather than several key strokes searching for it
3. The 3G keeps you always online and always connected. I recently ventured on a 4 hour road-trip and far away from home, it's a luxury to remain in touch
4. Maps with integrated GPS provides you driving directions - so throw that paper and pencil and that printer. While it may not be as good as the navigation devices (no point-to-point directions, voice activated, automatic re-route), it is pretty useful none-the-less
5. iPOD comes integrated, so your favorite music library comes with you at no extra device
6. Locating your favorite POIs (points of interest) especially when you travel - e.g. finding the closest gas station or Starbucks coffee or Roundtable Pizza
   
7. And lots more

Issues with the iPhone

1. The 3G connection is not reliable and very slow once you leave certain hotspots. Caltrain does not have good connection. Apple provided a patch to fix this problem but for me, the problem still persists
   
2. Sometimes the phone is slow to touch and response especially when it cannot connect to internet
3. Don't know whose grand idea it is (Apple or AT&T) but international text messaging is not included in the iPhone 200 package which is a pain since I text family in India a lot
4. The battery depletes very fast when you use the iPOD or when you browse the internet - this is a pain when you are on the road. Ah! but that means one needs the car charger
5. Not compatible with Bluetooth v1.1 and below. Sadly I had purchased a Bluetooth headset just 6 months ago, so more wasted investment
   

Overall - a good phone but still for early adopters.
