I know your pain. I bought an iPod Touch which at the time was an iPhone without the cellular radio. I thought that if I like using the iPod Touch more than I liked using my Pre, I would think about replacing the Pre with an iPhone. I loved the glass screen on the iPod and how thin it was compared to my Pre. The screen on the iPod made playing games a little more enjoyable. I know the iPhone was a little thicker but not by much and it was still thinner than the Pre. I missed the slide out keyboard from the Pre but I had so much respect for accuracy and ease of use of the iPod's on screen keyboard. I loved the way the music app looks on the iPod. I loved having more apps available. I loved the build quality of the iPod.
With all the pluses I just listed for the iPod Touch which were essentially the same as for the iPhone you would have thought that I would have replaced my Pre with an iPhone. Didn't happen. Lets just say that the experience was not like the reviewers said it would be. Although the iPod/iPhone had a lot of apps, I did not want or need any of them. I essentially downloaded the same apps that I had on my Pre with the exception of Bad Company 2, which was not available for the Pre. My biggest grip was the user interface. Holding the home button, waiting for the little tray to pop up, and then scrolling through a bunch of icons just to switch to another running app was painful. I didn't understand why other iPod/iPhone users put up with that. Why even have multi-tasking if you have to go through this? It got to the point that I just gave up, hit the home button once, found the app icon in the launcher and press it to go back, which was essentially the way the iPod/iPhone worked without multi-tasking. In webOS you just pressed the center button and scrolled to your app running in a card like window. Almost like on your computer. When you are done with an app you toss it off the screen which is a lot more fun than closing an app on the iPod/iPhone. The notifications were the next pain. You get a pop-up notification right in the middle of the screen while you are in the middle of doing something. You had to stop what you were doing to dismiss it. I can't remember but I think that it didn't even switch to the app once you press the notification (I could be wrong, I haven't used it in a while). In webOS notifications appear on the bottom of the screen for the Pre and on the top of the screen for the Touchpad. They are out of the way and you can ignore them if you want. You can also scroll through multiple notification and dismiss each one at your leisure. If you press on the notification in webOS the application associated with that notification opens up. Pure genius. I also hated how non-Apple apps would be essentially paused if I had to switch to another app. If I wanted to listen to a song on Youtube, the video would pause while I switched to another app instead of run in the background. In webOS only certain apps like games will pause in their card while you switch to another app. Everything else will still run in real time while you switch to another app. So in webOS your Youtube video will still play while you are in another app. I also hated how I had to dig through menus on the iPod/iPhone to turn on/off bluetooth, wifi, etc. In webOS I just press the digital clock in the upper right corner of the screen and a drop down menu would appear allowing me to handle all of those task on the fly without digging through multiple menus. I could not sync all my accounts on the iPod/iPhone. The calendar and email apps were limited. I had to jailbreak the iPod to add additional features that I took for granted on webOS. I found myself reaching for my Pre more and more. Even to play games, so I abandoned the idea of getting an iPhone.
I used my iPod/iPhone experience as an example because the iPad is essentially a bigger version of the iPod. I hoped that Apple would add some additional usability features to the bigger screen but they just concentrated on making the apps fit the extra real estate. Usability on the iPad is essentially the same as the iPod. What a shame. For such a popular device with so many apps it is such a pain to use. That is unless you are focusing on doing one task at a time. The addition of Flash on the Touchpad was the final nail in the iPad's coffin for me. At least you can view the real internet on the Touchpad's ten inch screen.
I get into some heated arguments with iPad users on these forums because I feel that the iPad doesn't offer anything useful to me, other than being pretty. It is way too expensive not to offer me a compelling reason to replace my laptop or even a netbook. Each offer more features. WebOS is the selling point for the Touchpad. It can handle my workload just like my laptop.
