Rather than be designed to run on a wide range of screen resolutions, form factors, and platforms, WP7 is designed to focus on a "class" of devices. Each class is defined by a set of hardware specs for a chassis.

There is a baseline set of Hardware components required, on top of which the chassis specs are applied. The base set of HW components are:
-ARMv7 based applications processor (compared this to ARMv4 for WinMo 6.x)
-Hardware accelerated DirectX and Direct3D (compositing is a big feature in WP7 and without HW accel won't run at an acceptable framerate)
-Capacative multi-touch screen
-Camera
-Bluetooth + Wi-Fi
-FM Radio
-A-GPS
-Accelerometer, compass, light, proximity sensor

Microsoft provides a set of built-in drivers for these components (1 driver for each component), to simplify the development process for the OEM. The OEM is not required to use these exact components but doing so means they don't have to spend time developing drivers for them (MSFT provides source and PDD bits) - so these are likely to be the components we find in first-generation WP7 devices. There is currently one main development platform and that is the QSD8x50 (snapdragon).

These components are in what's termed the "Silicon Catalog", and they are:
-Accelerometer - Bosch - BMA 150
-Compass - Yamaha - YAS529
-Ambient Light Sensor - Capella - CM3612
-Proximity Sensor - Capella - CM3612
-Wi-Fi - Atheros - 6002
-FM Radio - SiLabs - 4705
-Digital Camera - Aptina - MT9P012 (5MP)
-Capacative Touch Controller - Cypress Semiconductor - 301x series


The first chassis to be targeted for initial release is the "Performance Chassis" - adding on top of these base requirements a WVGA screen.

Other chassis will follow after the initial release - I would expect there to be a higher class/chassis added later. Currently we run 192 DPI for WVGA and the current WP7 build has support for 262 DPI (incomplete as of this writing) so we can more than likely expect to see larger "tablet" styled devices later.

In Xda-Developers we trust...

Yep michialdu, Xda-devs have a wp7 section for months, and i thought this info is useful to developers, so i posted here. And wrote there: Credit again to Da_GNARF. So i think what i've done is correct

I hope they'll be able to release WM7 for my Diamond2...
I'm pretty sure it'll be released for MDAIII (HTC Blue Angel), I'll need to find it in my drawer if so...

First of all, it's WP7 Not WM7. WinPho 'n WinMo. See the difference?

I don't think so it'll be released for the diamond 2... It has only a 528 mHz CPU. The other specs are looking promising. (5 mpixel, WVGA) Does it has a resistive or capacitive touch screen (i think it's resistive, correct me if i'm wrong). Well, if they'd release it, it would be extremely sloooooow. Have you seen it running on a HD2? It's pretty slow too, but it has an 1gHz CPU.


The Harrier with WP7. Man are you serious? I don't think a 6 year old PDA can handle WP7

Well, I guess they'll at least try. Do some magic with drivers, make the system more lightweight and stuff...

And actually I wouldn't be too surprised if they would release one for that old device... WM 6.5.x runs pretty well on it...

only time will tell

Exactly.

Wp7 Will NOT be compatible with ANY old phone!!!

the ONLY phone that has the req for Wp7 is the HTC HD2 and Microsoft said that they will NOT launch a offical OS update for it
BUT!! XDA said that they have some one that got it to work ont he HD2

hd2 Wp7 problem = gona be SLOW , and most apps wont be compatible

Microsft req for ALL Wp7 ( meaning they will all have same hardware specs):

- 1GHz Qualcomm Snapdragon core
- Multytouch
- quadband EDGE and triband HSPA (850 / 1900 / 2100MHz)
- 512MB ram
- 5MP camera (720p i think 24FPS)
does are the MAIn req ( aside from GPS and other things )

after erading ont his phone on over 20 websites they ALL seem to ahve the SAME spec , only thing that changed whats the STATING apps and the LG Optimus having the FULL QWERTY keybored and the Samsung focus/omnia 7 Having the S-AMOLED

I don`t think WP7 will be compatible with any old phone.I guess HTC has the requirement for WP7. I do feel that only time will tell if it has got any sort of compatibility with other phones or not but seeing the requirement , it will be quite tough.
