Samsung Omnia W I8350

This has Super AMOLED - one of the best available displays (better than Lumia 800 and 710).
It has a secondary camera for Video call which is not there in Lumia
and importantly it is less priced compared to Lumia's.
Nokia, you don't have any more chances to get the market share again that you lost already.

Windows Phone OS has relatively very strict requirements. Keeping that in mind, Samsung I8350 is as cheap as windows phones will get (atleast until Windows Phone Tango has arrived). Nevertheless it flaunts a 1.4 ghz scorpion processor, 3.7 inch SuperAMOLED screen and a metal body. Not bad, Samsung!
The OS on the other hand is not as versatile as, say, Android, but it may come as a breath of fresh air to some. Simple, fast and beautiful. However over-dependence on Zune, no Bluetooth file transfer, relatively less apps and no true multi-tasking can’t be overlooked.
Pros:
1. Albeit being at the bottom of the food chain (for Windows phones), the cpu and gpu(1.4GHzQualcomm MSM8255Snapdragon CPU, Adreno 205 GPU, 512MB of RAM) don’t scream it. On the contrary, they are as good as any windows phone out there.
2. 3.7” SuperAMOLED is one gorgeous piece of hardware (It has pentile matrix though).
3. 8gb inbuilt storage.
4. Mobile Office looks as good as it has ever on any OS.
5. Metal back gives it a sturdy and premium feel.
6. 5MP snapper does well in decently lit environments
Cons:
Most cons would be due to limitations of the OS as has been listed earlier and is obviously common to all windows phones.
1. Other than those, the video recording is not something to boast about.
2. The speaker is relatively quiet.
Competition:
The most obvious alternative is Nokia Lumia 710. Lumia phones have an edge over other Windows phones in having nokia drive. 710, however, is all plastic and has a ClearBlack LCD(not AMOLED). But its price may fall in coming months.
HTC Radar comes with a 3.8” S-LCD and 1 ghz scorpion processor, and as of now, is priced higher than Omnia W I8350. If price is not a constraint, you can probably go all the way up to Nokia Lumia 800, if you find its polycarbonate body irresistible.
Omnia W I8350 faces two hurdles. One is the hype that Nokia has created during its launch of the Lumia duo. It is almost Nokia Lumia or any other OS sans windows. The second and as important is the presence of many Android alternatives at this price. Sony Ericcsson Ray and Sony Ericcsson Neo V from the Sony family and more importantly Samsung galaxy R I9103 with its dual core processor may well be worthy competitors.

This comes from an early adopter and huge fan of Google's Android OS.

I have been amazed by Android's capabilities. Be it multitasking, or flash-compatibility. But where the Windows Phone just blew my minds off is by making a lot of functionalities actually usable. And how.

I used it first at a retail outlet, and I fell in love with how the UI just moved around to my every swipe and tap. It's been a week now and so far it's amazing. The UI is just incredible and knocks the socks off iOS and Android. It is blazingly fast. It switches between apps effortlessly and now my favourite pastime has become 'see if you can beat the Windows Phone.' Trust me, I am not making any friends here.

It books tickets faster than any phone here.
It accesses and posts stuff on facebook faster.
Games load faster and can be switched between easier.

And grudgingly, a few cons:
- No extendable SD Card memory. This would've been a deal breaker. But I am fine since only my iPod can carry all the songs I have. That's over 50GB of music.
- No LED notification. For one you won't be disappointed that no one's texted you.
- Whatsapp's WP version is wishy washy at the best. Sure, it functions. But not as snappy as other Windows apps. I hope it gets better soon.

Nifty touches:
Xbox Live Avatar
Live Tiles, Contact Grouping
Character seeker while typing (VERY innovative; it's a use-it-to-know-it thing; type a long sentence and long press the text field to bring out a hovering cursor)
Switching between previous images and camera mode with a single swipe
Camera button can unlock screen and open camera mode (ready in 2 seconds; kid you not)

If you are worried about the availability of Apps in Marketplace. So far, the only apps that I have missed are Google Currents and Homerun Battle 3D. So it's not that big an issue.

Do try a Windows Phone hands-on to know what I've been talking about. There is very little chance that you will be disappointed. I know I wasn't.

Main disadvantages:
Non-expandable storage
No mass storage
Zune-only file management and sync
No Bluetooth file transfers
No Flash (nor Silverlight) support in the browser
No DivX/XviD video support (automatic transcoding provided by Zune software)
