57% of Android Market Applications are free & just 34% of iPhone applications..

As X10 is rooted now, customization is just a matter of time :)

How smooth & fast iOS is, you can read below from a site:

Not talking about signal-issue, it's not a bug, it's fault actually.

The Meh: FaceTime

I tried FaceTime on a few occasions from various WiFi connections. It seems the most important factor in the quality of video calls is the WiFi connection. Attempting to FaceTime with a friend using public WiFi at a Starbucks was a terrible experience, but it was far better when both of us were on secured private networks in our homes. Even then, however, the call failed once and we had to redial each other. Hopefully this will get better in time, but for now, once the novelty of video calling on a mobile device wears off, FaceTime may not be that exciting.

The Huh? Strange Bugs and Quirks

The iPhone 4 is buggy. Very buggy. One of the most annoying ones, especially for a user like me who takes a lot of photos, involves the deletion of photos from the camera roll. Almost every time I delete a photo while viewing the camera roll, some error occurs where the photo is replaced by an immovable black box.

I have noticed, however, that deleting items while viewing them (by tapping the trash can icon while viewing a photo, for example) does not produce the same problem. It only seems to occur when marking one or more items with the red deletion check mark that it happens. Usually, syncing the device in iTunes will fix the issue, but sometimes that will even make things worse. I have had several photos disappear and deleted videos reappear unplayable in my camera roll, which was only fixed with another iTunes sync.

The mail app is also very bug-prone. I noticed some strange things happening with mail back on my 3GS before switching, and now they are better, but still odd. Before, emails would appear and quickly disappear in my inbox, only to be re-downloaded, or sometimes not. Now, the mail app seems intent on peppering my inbox with emails from the distant past (or future depending on how you look at it). An email with no sender, no subject and no content, sent on 12/31/69 has appeared on more than one occasion, though it has been less frequent in the last day or two.

The Multitasker's Dilemma

The other source of bugs comes from apps that do not support or properly implement the phone's multitasking capabilities. I have had some apps break or become unusable, and the only solution was to delete them from the multitasking menu and "relaunch" them. While this is not really Apple's fault, it does, however, create a new level of thinking for users when it comes to their apps and troubleshooting.

Previously, apps started from scratch whenever you clicked their icons. Now, for better or for worse, some apps resume from their last active state. In the case of messaging apps, this can be useful. In the case of apps like Settings, it can be annoying when you last closed the app after digging several levels deep into various sub-menus.

To truly "relaunch" an application, users must now click the home button, then double tap the home button again to launch the multitasking menu, then hold down their finger on an app until it begins to wiggle, and finally click a red minus sign icon to remove it. In most cases this isn't really necessary, but when an app is not responding correctly, I find myself using this tactic as a crude form of "ctrl+alt+del." Here's an example of when this problem occurred.

One Hot Phone. No Really, I Mean Hot!

When out doing errands, a strange thing happened with my iPhone. I found myself with 5 bars of signal and 3G service but unable to refresh my stream of messages on my Twitter application. It couldn't be the reception, I had 5 bars, so I clicked the home button and then re-entered the app, but it still didn't work. That is when I deleted the app from the multitask menu, effectively force quitting it, but another attempt still didn't work.

Then I tried other apps, and I quickly discovered nothing was working. I made sure the phone wasn't trying to use some random WiFi, so I turned WiFi off. Still nothing. I flipped airplane mode on and off to reset the connection to AT&T, but that still didn't work. Then I noticed how the phone felt in my hand - it was hot. Very hot. And not just because I was in 100 degree Arizona weather. It still felt hot in my cool air conditioned car.

The phone had overheated, and while I could navigate to apps and menus, sending or receiving any data was impossible. I turned the phone off and immediately noticed the temperature of the device drop significantly. I turned it back on and all was back to normal, but as you can see from this example, the complexity added by multitasking changes the way users will approach troubleshooting problems on their device. The entire time I was trying to no avail, the phone was resting in my palm, a testament to the paranoia also caused by the antenna.
