There's new phones coming out all the time... so undoubtedly a trip to your local phone retailer is going to net you something, either right now or in the near future...
It's another real case of "Horses for Courses" too... I've used Windows Mobile, Blackberry, Android, Apple, even PalmOS... I spent nearly 3 years as a Converged Devices Specialist trying out a new phone every week for a variety of different user groups... and different models were chosen even within the same OS family because of different physical use-cases, or different software requirements tied with specialist hardware etc...
I recommend the iPhone to most people these days, because of the "it just works" scenario, and I don't like to be asked for ongoing technical support if I recommend something more complex... it's the same reason that iOS and Blackberry are still the two major players in the business arena... they are easily supported... but you've said you want something different...
Unless you're willing to go the Blackberry route... they have some nice hardware these days, but even with the re-vamped OS 10, they are losing market share, and app availability and interoperability between platforms is still trailling significantly behind Android and iOS...
Windows Phone is another option... WP8 is gaining traction, and there's certainly more apps becoming available, I'd say they are probably ahead of BlackBerry but behind Android/iOS at this point, and will probably catch up at some point in the future...
But if you're looking for apps, Android has to be the way to go... like I said before, these phones are a dime a dozen, if you go into a store they will have something... go into several stores, and you'll have several options...
I'd also really consider your choice of carrier too... it's been a long time since I've had to pay for my own mobile bills, and I know that people go with Optus or Vodaphone or *shudders* resellers like Virgin Mobile which just pile more users onto the Optus network, but based on my experience in metro and regional and even remote areas within QLD, and time spent interstate and in other capital cities, I've never had a single issue with Telstra... but colleagues and other travel companions have complained constantly about (especially) Optus and Vodaphone...
Each to their own, but depending upon how serious mobile coverage and availablity is for you, it may be worth investigating whether another carrier is going to give you more of what you want, too...
PS: Something you may be interested in if researching all the different options available to you is the network of Smartphone-specific websites known as the Mobile Nations Group:
http://www.mobilenations.com/ They have various sites dedicated to the major OSs and manufacturers... lots of news and relevant articles, but several of them have buying guides too.
