iPhone vs Windows Mobile

Now, as iPhone is out it is about time to compare it to Windows Mobile. I must say that I haven't seen iPhone in alive as it is released only at U.S. at the moment, but I have read many reviews, and I feel confident that I wouldn't feel surprised facing the real product.
First of all iPhone will be very successful. It is sexy, and sexy products are always successful, unless they are a total garbage, and iPhone is not. However, I think that readers of this blog are looking for functional device, and I'll try to direct my comparison in that way.

• First of all, this product has no intention to be best mobile phone. It has intention to be best gadget. It puts calling at the same level as mail, Internet and iPod (music and video). And I think that for most people it is not. It is not even on the same level with regular phones, and not to say Palm Treo where it is enough to type just first several letters of name to call (in both Windows Mobile and recent Palm OS releases). So, the question is whether you are ready to sacrifice this for additional functions.
• Messaging is also less capable than average phone, and again much less capable than messaging with phones with full keyboard (like before mentioned Palm Treo). This specially relates to SMS.
• Internet is great. This is first mobile phone with real capable browser (on Windows Mobile you may try Minimo - Firefox for mobile devices, but there are just early preview versions not meant for the end-user). This is definitely great. But you use your mobile phone browser just in case that you are far from any computer, as its screen and price of browsing can't compare with the real thing. So, if you use this so frequently, it is a great news. For most people a welcome improvement, but not a switching point.
• Multimedia is where this phone beats all other phones. Though, most smartphones makers always thought that this is not the most important area for their users. But at this point it is a welcome change, and I think that others should make some improvements. Again, it is not so critical. You can't expect users to use this option so hard, as it drains battery, and it is not likely that one will risk that. This specially relates to videos. So it is more likely that people will use iPhone for some short personal movies than for the real movies (though at this point its software doesn't support recording of video). On the other side, iPod like functionality is more important - it drains battery less and is much more likely to be used. However, with 4Gb of memory you are more likely to turn to shuffle (there is also version whith 8Gb which should be more capable in this situation.)
