[AT&T Samsung Galaxy S II Skyrocket SGH-I727] Merlyn_3D:
I agree with you yozh. I've also been with xda since the WinMo days. I'm facing the choice between the iPhone 4S and Skyrocket. To be honest, I'm probably going to sell the Skyrocket and go back to my 4S for two main reasons: battery life and the skyrocket HD that's around the corner. I feel like I shouldn't have to worry about pulling my phone out of my pocket to use it. With the skyrocket I"m always worried because of the crappy battery life. I hate reading all the iOS bashing here, come on guys be fair. Who are you trying to convince here?

I've put together a list of items I miss from each phone while I'm using the other below...

Here are the things I've missed about my iPhone in the couple weeks I've used my Skyrocket:

battery life

Better camera, the camera on the 4S is faster and clearer, especially in low light situations

Better video, in all the comparisons I've seen between iPhone 4S' video and the Skyrocket videos, it seems like the iPhone does a consistently better job with colors and dynamic range than the Skyrocket.

iPod interface, all of our cars have an iPod interface of some sort and it's really easy to use with the iPhone, not so much with Android phones. This sucks because I feel like it's vendor lock-in

AirPlay, it's so liberating to be able to AirPlay the TuneIn app, or Pandora, or the iPod to any of my TV's or computers. The closest I can come to doing this on Android is by setting up Squeezebox server and trying to find clients for my computers, which hasn't been easy.

battery life

Exchange Tasks, iOS5 adds excellent support for syncing of tasks to iOS from Exchange (including task folders)

Location-based Reminders (location based reminders are awesome)\

Retina display, this screen is just f*cking gorgeous, even if small for some. It's also consistently more accurate at displaying pictures than the Skyrocket's.

one handed use, the Skyrocket is much more difficult for me to securely hold and use one-handed because of the larger form factor

call quality, iPhone's speaker and earpiece sound cleaner to me than the Skyrocket. Samsungs in general have always sounded a bit tinny to me, even in the flip phone days.

Multiple exchange calendars synced to the OS calendar (instead of one per exchange account)

Quality of apps, everything, even equivalent apps, seem to look more refined/polished on iOS. My experience has also been that iOS apps get preferential treatment in new features or new app rollouts.

App support for push notifications, any iOS apps that support push support in a true push fashion, I've only found 2 android apps that support Google's C2DM push notifications (which would really help with the battery life issue).

Physical Silent mode switch, I can flip this without taking the phone out of my pocket on the iPhones, can't do this on the Skyrocket.

HTML Email Formatting, what can I say, it's done exactly as it should be on iOS, Android still hasn't gotten this right requiring me to try and zoom out or pan around most HTML formatted messages.

Syncing photos from Aperture, not iPhoto. I can't figure out how to get my Aperture libraries to sync over.

did I mention battery life? Seriously, I get 1.5 to 2 full days even when using the 4S a moderate amount. When lightly using the Skyrocket, I get about 12 hours (I'm in an LTE area). This wouldn't be as much of an issue if I could find an OEM quality extended battery, but still. The iPhone 4S' battery is around ~1400mAh, the skyrocket battery is ~1900mAh. iOS does something right when it comes to power efficiency that Android just hasn't managed to do yet.

power management, don't tell me I have to police whether Wifi, GPS, and BT stay on or not. I should be able to leave all three on and get great battery life. The iPhone has proven this.

consistent updates, Apple's track record of updating iOS is very good, Samsung's track record is quite terrible

reception, iPhone 4S does a marginally better job holding onto 3G in areas where the Skyrocket displays EDGE only

build quality, this one doesn't even need explaining

lack of carrier branding, I dislike AT&T but consider it a necessary evil. I don't want to see there logo every time I look at my phone. I dislike all the crap they preload onto the phone too. I wish they had a GSM/LTE variant of the Nexus for the 'Google Experience'. I'd be all over that.

Things I miss about the Skyrocket when using my iPhone:

LTE, speeds are ridiculous, it's almost better than WiFi

Larger screen is easier to read sometimes, better for watching videos if not as crisp as the iPhone

ease of root, once you root, the phone is yours and you can pretty much make it do anything (except make the battery last as long as the iPhone)

plethora of ROMs and Kernels to choose from, it's actually quite fun getting into the nitty gritty and putting ROMs together.

Ability of apps to interact/mingle with each other. It's nice to be able to install an application and have it feel tightly integrated with the OS, iOS simply doesn't allow this.

expandable memory, although even with a 32GB SD card (max supported), I can't match the 64GB in my iPhone, but it is cheaper

LTE, again, LTE is ridiculous

standardized microUSB charging port

NFC, oh wait, it's disabled, come on AT&T. I've seen Google wallet work with express pay systems around town and would love to use it except that I can't with this phone.

notification drop down, it's still better on Android than in iOS.

App market refunds

Google Music is pretty damn cool on Android
