Well, I be happier to give you a more precise comparison.
You said,
1. Bigger display - Sorry, but both have the same display size and colours. i.e. 240 X 320 Pixels and 256K respectively.
2. Better, louder stereo speakers - I am not sure about the loudness, but K810i definitely has better speakers.
3. Better quality higher resolution video recording - I can't believe you actually compared the two cameras. Try it out yourself. You'll know the difference. As for stats, K810i has
- Photo fix
- BestPic™
- Image stabiliser
- Red-eye reduction
- Video stabiliser
- Xenon flash .
4. Lower price of memory cards - No comments here.
5. Presence of both, EDGE and 3G - You are right here. And as you guessed it right, since I don't use it, I don't need it !!!
6. Much better built-in browser - It's more of a personal choice rather than statistics. So, no use of arguing here.
7. Ability to read office documents and pdfs by default - Does the "default" thing make a difference ??? Don't be a kid. Both serve the same purpose.
8. Contacts and messages can hold unlimited entries respectively - Practically speaking, each one can hold unlimited entries.
Now, let me add a few more points:
1. Phone Memory - N73 has 42 MB shared memory. K810i has 64 MB Internal Memory.
2. Speed - Even a layman will agree that K810i is way faster than N73.
3. Dimensions - K810i has slightly smaller dimensions and less weight as compared to N73. I repeat, it's only slightly though.
4. Looks - Differs from person to person. I prefer K810i.
Sorry for such a long post. I had no option !!!
1. I was talking physical size, not resolution. Both have the same resolution, but N73's display is 2.4" big compared to K790i's 2.0".
2. I guess you never heard N73's speakers. They're nearly twice as loud as that of K790i.
3. Why don't you read properly? I was clearly talking about the video recording whereas you gave me K790i's still image capturing features. Can you use Xenon flash for video recording? K790i can record video in QCIF resolution in 3gp format whereas N73 can record videos in CIF resolution in mp4 format.
4. You don't need it now. But you'll soon need it. 3G is coming to India BTW.
5. There is no personal choice issue here. S60 web browser is universally hailed as the best browser on any mobile phone. Once you use it, you just can't go back to standard cell phone web browsers. Its just like using a pc browser. I suggest you read about its merits and features.
7. Of course it makes a difference! I buy an N73, I open the box, take it out, connect it to my pc, transfer the pdfs and then view it on the phone. No need to bother with any additional software downloading, installing, etc. Can I do the same in K790i? I think not. Not only will I have to bother with downloading additional software, the quality of software itself (being Java) would be a concern and how well I be able to view my pdfs.
8. No. There is a limit to how much messages and contacts K790i can hold. I don't know the exact number of messages, but for contacts its 1000. For symbian phones, it depends upon the free memory. Considering messages and contacts consume memory in just bytes, what you have is a practically limitless number of contacts and messages.
Now about the points you posted:
1. Makes no difference if I have a 2gb card (which as I've said are dirt cheap now).
2. Agreed. Smartphones are always slower than standard phones. Nothing new here. I expect users to know this fact. People demanding ultra fast speeds should stay away from smartphones.
3. As you said, its only slight.
4. I prefer N73. I wanted to include this in my earlier list of advantages, but since its not exactly a feature, I didn't include it.
I don't mind long posts. As long as they're logical.
