How much more productivity are you getting from the iPhone than you were from your Android phone? What kind of work are you doing with it? Give some of examples of what you like better on the 4S.
Have you never used iOS?
One of the first
big things for me, my friends, and co-workers is the
VPN support.
iOS, out of the box, supports Cisco IPSec VPN connections. Try and find that on Android.
The Cisco AnyConnect client also works great. If you check the Android Market, it mentions having to root/jailbreak your Android devices to install the AnyConnect client (which makes it invalid for any of the Google Market media due to DRM restrictions). There are no such silly hoops to jump through on iOS. It just works.
Until we can connect with Android devices, we won't even consider them at work. No support for Cisco IPSec, poor support for Cisco AnyConnect, and complete system lock-ups on Android devices we've tested with L2TP/IPSec and PPTN VPN. It's obvious such few professionals use the platform, as those should be the first things working.
A second big thing is how light-years ahead Mobile Safari and the Mail client are compared to anything on on Android. Regarding the browser, issues with performance, page re-draw, and page rendering just make it not fun. I find myself looking for more site-specific apps (CNN app, forum apps, etc) than bother using the terrible Android Browser
Safari on iOS works as well as Safari on the Desktop. The Android mail-client is terribly ugly, as well. Both the performance and the weird background-downloading it does bothers me.
A third big thing is the app selection and quality. Have you seen anything as polished as iTeleport (VNC), iSSH, or iTap RDP on Android? Apple has
strict rules for App design, and it really shows. The experience to the end-user is just second to
none. The layout of applications and standardized ways of each program working means every new app is learned just as easily as the last.
After we make our VPN connection, the remote-control apps allow us to easily and gracefully manage our Windows, Apple, and Linux servers and Cisco switches. Just having a "VNC app" on Android doesn't give the same experience as it does on iOS. From things like fine-control over how the mouse cursor works (finger as the mouse, screen as touchpad, mouse-acceleration, etc), managing devices from our iOS devices works as well as being at a Desktop.
A forth big thing are the games. Yeah, they don't help with productivity, but having the biggest-name games on your device from Square, Konami, Capcom, EA, and others always helps in the down-time at work.
A fifth big thing is how well the OS controls everything. It's not the wild-west of "anything goes" like on Android. The OS controls the Notifications, push, sync, and backgrounding processes. It's not left up to poorly-written apps to decide how my devices function. I don't have to worry about battery issues, or taming rogue programs, or some app eating up background data because I forgot to dig through its options. Android is similar to Desktop Linux as it is a wet dream for someone who wants to micro-manage and tweak every little thing. iOS works great for someone who wants a device that just works. I can get work done without having to worry about babysitting my phone or tablet.
So yeah, iOS allows you to be way more productive than Android. That's probably why iOS/iPhone/Apple is consistently reported as #1 by their many,
many pleased customers. I've used Android (I own three Android devices!), I've used Windows Mobile, and I've used iOS. Like so many others, iOS is the best option out there, by far.
The enterprise is really embracing iOS. BlackBerry is yesterday's stuff. Android is just seen as trash. It's been out since 2008 and is still a joke. Maybe things will get better after 4.0 is released. People got a taste of iOS back in 2007, and it was in full-gear by 2008-2009. Android is years behind.
