Apple iOS 5 Review

AirPlay was a cool feature introduced with iOS 4.2 that allowed users with an iDevice and an Apple TV to stream video, music, and photos over a local wireless network. I personally never understood the appeal until earlier this year, when I stole my friend’s Apple TV and hooked it up. Not including game consoles, it’s become the single most-used device I have in my home theater. Seamlessly streaming music and YouTube from my iPad, or friends’ iPhones and iPods when they come over, is a phenomenally useful feature to have. It’s like Remote, except for your TV. With iOS 5, Apple has given AirPlay a very ambitious makeover, and given my recent love affair with it, well, colour me intrigued.
If you have an original iPad, iPhone 4, or iPod touch 4, feel free to skip over the rest of this page - you’re going to end up being jealous. Those of you with iPad 2’s or an iPhone 4S now get the option of mirroring your entire iOS display over to the big screen. We’re talking everything - the lock screen, the endless grid of icons that substitutes for a homescreen, the multitasking bar, Safari, third-party apps, FaceTime video calls as mentioned earlier, anything that you see on your iPad or iPhone screen is wirelessly duplicated on your TV.
To enable it, bring up the multitasking bar, swipe all the way to the left, and hit the AirPlay button. Select the Apple TV, and underneath will be a switch to turn mirroring on or off. Push the slider to “On”, wait three seconds, and voila, your endless grid of icons is smiling at you from the TV. This is basically like the HDMI screen mirroring you find in Honeycomb, except wireless. Oh, and instead of a $5 HDMI cable, you’re using a $99 Apple TV. The Apple TV has to be updated to iOS 5 as well, part of the Apple TV Software version 4.4.
In practice, it all works pretty well. The latency isn’t bad at all, and in general things move fluidly across both screens. The one truly annoying feature about it is the aspect ratio. I feel like this won’t bug me quite as much with the iPhone 4S and its 3:2 screen ratio, but with the iPad 2, there are some rather noticeable black bars on either side of the display image. Yes, this is a given, because the iPad has a 4:3 screen ratio, but displayed on a 16:9 TV, it looks a bit odd.

"Unfortunately, iTunes Wi-Fi Sync asks that your phone be connected to a power source for the feature to work. This shouldn’t be too hard to grasp considering the massive power drain issues people would have inevitably faced had it not been otherwise."A quick but notable clarification in the review which gives the impression the wi-fi sync function requires a device to be powered to work. It needs to be plugged in to work automatically once a day. However, a device can manually be synced over wi-fi without being plugged in. Go to settings -> general -> iTunes Wi-Fi Sync and hitting the Sync Now button.

On the last pic in the find my friends section, you blurred out the account name at the top,. but not where it appears again at the bottom of the screen.teetee1970 - Tuesday, October 18, 2011 - link
You mentioned the newton force etc to take a picture. You can actually take pictures now with the headset using the up volume button. So you could hook up to a tripod etc or set the phone down somewhere and click away as fast as you can press the buttons on the headset. You could probably use a bluetooth up volume button too.Guspaz - Tuesday, October 18, 2011 - link
I've yet to have WiFi sync actually automatically sync my phone when plugging it in for the night. Perhaps iTunes must be left running on the computer, but that kind of defeats the purpose of automatic sync; I'm not going to leave a bloated app like iTunes running 24/7 just in case my iPhone decides to sync.If this is a requirement, WiFi sync will be largely useless for me until they can at least have a service launch iTunes on the PC when the phone wants to sync.

Yes, iTunes has to be running for the wi-fi sync to initiate automatically. No, the iOS device won't launch and then quit iTunes.One other thing I've noticed is that leaving iTunes running with wi-fi sync enabled is an enormous power drain on the battery on my iPhone 4. I've noticed my fully charged phone will be down to 40% charge by the morning. Of course, if you leave the iPhone plugged in all night, it will still be fully charged in the morning but apparently, there's a lot of power-draining activities going on between iOS device and computer during the night. This is one reason I've decided not to use auto wi-fi sync since I don't want to keep iTunes running and unnecessarily using power overnight. I still like the wi-fi sync option a lot but I manually sync wirelessly and then quit iTunes.

I was a Palm/WebOS junkie since it came out."A company that executes consistently may not be competitive on day 1, but after a couple years of progressive iteration it may be a different beast entirely." sums up what WebOS failed to do successfully.

Thanks for including results from previous iOS versions to see the evolution in performance as well as the analysis of iPhone 3GS and iPad 1 performance.http://www.barefeats.com/iph4s01.html
I was wondering why GPU benchmarks weren't included? The results at Barefeats show that Apple seems to have much improved GPU drivers in iOS 5 compared to iOS 4.3.5. Devices seem to show around a 25% improvement in GLBenchmark for instance. It would be good if you could validate this result in GLBenchmark and GLview as well as add in the iPhone 3GS which Barefeats is missing.
And do you know how GLBenchmark's online results database reports it's scores? For each device, in the details they seem to list multiple GPU driver and OS versions, which makes me think they are using a running average of submissions. Seeing performance changes with OS version, that would make he GLBenchmark online database very inaccurate. It's great that you are able to run the benchmarks on your own devices so that the results are unambiguous.

I haven't seen many comments about the disadvantages of using iMessage. Here's some I've noted:iMessage costs more when not on wi-fi. I pay a flat $6 per phone for everyone in my family to have UNLIMITED SMS/MMS. Or if I use iMessage while away from Wi-Fi, it counts against my LIMITED $15/200MB per phone data plan.
Also, I've found SMS to be more reliable than data service in congested and rural areas. Try posting a Facebook status update or any other data service from a crowded football stadium, vs. using SMS. SMS always wins.

Most people don't have it like that. But then again, most normal people use Whatsapp. It has really been a revolution for me and my friends.P.S. I have 50 sms free per month, and 1GB of traffic.

iMessage packets are very small though. You would have to send on the order of 8000 iMessages per month to use even 1% of your 200MB plan. I'm guessing concerns regarding data plans are also the reason why Apple implements compression for iMessage MMS's when even one client isn't on Wi-Fi.
