WRFU for Windows Mobile?

It has been considered, but at the moment there are simply far too many 'Windows Mobile' platforms, each customised by both the manufacturer and the telephone company.

Which version of Windows Mobile to support? 6.0? 6.1? 6.5? Or 7.0 when that comes out next year?

What has been changed for each customisation? Some strip out certain functions, others don't.

What hardware? Some have touchscreens, some don't. Some have some other kind of pointing device, others only have a roller, others just arrow keys.
Some have real number and alphanumeric keys, others rely on an onscreen keyboard of various sizes.

What screen resolution - or even which aspect ratio?
I just had a quick look here: http://www.microsoft.com/windowsmobile/en-gb/devices/smartphones.mspx?13=&14=&57=1, and found three different resolutions each with a different aspect ratio on just the first page.

Basically, there are just too many different devices and operating systems that are all labelled "Windows Mobile" to have any confidence that something we write and test on (say) my phone would also work on your phone.

On the other hand, the iPod Touch and iPhone (of all versions) have the same screen, operating system and basic capabilities.

As well, there is the bonus that if you don't want a phone (with associated long-term contract etc), then you can get an iPod Touch for £140 or so and the same iRFR software will still work for you.

OK, thanks for the explanation, little did I know about all that stuff.  I'll look into the iPod Touch then.
