Here's my list of positives that no other phone has which is justification for me in sacrificing a couple of features.
1. It's Mac friendly.
2. Revolutionary touch interface
3. Two-finger stretching gesture
4. Two-finger tap-to-zoom out gesture
5. Two-finger pinching gesture
6. One-finger double-tap-to-zoom in gesture
7. One-finger scrolling gesture
8. One-finger flicking gesture
9. One-finger swiping/sweeping (depends on the context) gesture
10. One button design - that lone button on the bottom of the phone will take you back to the home screen, provide quick accessibility to the iPhone's list of applications, provide a quick escape from the depths of any application or settings screen and act as a clean up/clean start tool - all with one quick press.
11. Large 3.5 inch screen. Biggest camera view screen ever made.
12. Thinnest phone available anywhere.
13. High resolution screen provides 160 pixels per inch
14. The most readable text (fonts) of any handheld device ever made.
15. Largest dialing keypad available on any mobile phone for easy number entry
16. The stability and reliability and security that comes with OS X and LLVM.
17. That incredible scrolling with rubber band effects ? mirroring real physics effects
18. THE BEST mobile browsing experience... period.
19. Easiest conference call management I have ever seen.
20. A true web applications platform for a mobile phone. With Safari, now apps can be developed for any desktop computer and the iPhone.
21. Internet content is not determined by the carrier (who wants to sell the user something), as is the case with every other phone that can utilize the internet.
22. Coolest implementation of Google Maps I have ever seen.
23. Access to YouTube videos with no extra charge. This is unlike other offerings where carries have mobile video plans that use the walled garden approach: accessible only with a monthly charge and giving only short clips.
24. Widgets and applications that provide quick, good-looking and easy to use net based services.
25. Push-IMAP support like a Blackberry, not that fake pushing either.
26. Continual surveying of wi-fi availability with automatic switching. Previously joined networks are quietly and seamless connected to.
27. Appropriate and usable visual cues within the slickest user interface I have ever seen.
28. It doesn't have carrier logos plastered all over it.
29. It uses a quad-band GSM radio which allows it to be used in every country except Japan.
30. Context sensitive keyboard that pops up when needed. This is extremely useful and really well done.
31. Bizarre and unheard of concepts like "touching your music" and "Visual Voicemail" (random access) actually make sense in using the iPhone.
32. Voice mail scrubbing. Lets you scrub through the voice mail timeline to quickly get to where you want.
33. Voice mail is sent to you - like push e-mail. You can listen to and review your voice mail on a train or on a plane, without the need of carrier reception.
34. Coverflow browsing of music and media. Plus, you can flick an album and it spins around to reveal the song list to choose from on the back... just like physical albums.
35. The iPhone screen fa?ade can actually be quickly and simply wiped clean with its unique edgeless, no-bezel design. This is to say nothing of the specially selected screen material chosen for use with grimy, greasy fingers.
36. An external speaker (for speakerphone functionality AND iPod use) that doesn't get covered up when you lay it down like every other phone on the market. Thank you.
37. iPhone's antenna is located in the back part of the phone at the very bottom. Very considerate for those with radiation concerns. Never understood why manufacturers continue placing the antenna as close to your head as possible.
38. Fully charged battery will provide up to 6 hours of internet use, 7 hours of video playback, 8 hours of talk time, 24 hours of audio playback, 250 hours of standby time This is unbelievable performance.
39. Context sensitive, smoothly transforming control surfaces provide an intuitive user interface.
40. Big bubble editing lets you touch and hold the screen to get a zoomed in area of text for precise cursor placement with your finger.
41. The keyboard - I know a little bit about what they are doing to make this unique keyboard a success. Every little space on that screen is tracking and measuring and relating to every other little space. There is a great deal of processing power required JUST for the simple act of typing. And reading how your finger hits the screen and what part of your finger hits first and the total amount of space that it hits ? all in an effort to account for inaccuracies. There is a lot of research that has been done here. They even take into account a person's inability to accurately predict what part of their finger actually hits the screen. It seems that we fail to take into account the curve of our finger and how it actually hits the screen based on the overhead view we have in watching the screen as we type. Then of course there is the software based auto-correcting type of feature that analyzes which keys you MIGHT have meant to hit and figures out the word you wanted. And then of course word prediction. To this end, word prediction itself is also used in conjunction with a process of dynamically enlarging tap zones behind the scenes for virtually larger keys.
