[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] superpeca:
What OS to use...

Hi all, I tried them all on HD2 WM 6.5, 6.5.X,Froyo on SD,WP7 and finally stuck on Ginger in ROM. What is best for you depends on what kind of user you are. For example - I'm not into gaming on my phone, I don't have a facebook or twitter acc and couldnt care less about social networking,I use email extensively, care about outlook integration, office docs, use a lot of browsing, watch a lot of youtube and news aps...

WM 6.5(.X)

GOOD

- Looks great (the weather animations are so cool, the tabs are functional and fun way to use the phone)

- Has USB storage mode

- Has USB and WiFi tethering capability

- Can sync with outlook mail and contacts or any other mail with such ease that flashing and putting it back to running state takes less than 5 minutes

- Has a ton of GREAT GPS apps like iGo etc

- Best battery life of HD2 is of course on a original 6.5 ROM, nothing you flash will top that

- Skype works, although a very old version that you have to install yourself

- Can be used until the battery is dead and then recharged without a problem (not like android or wp7 ports)

- You can customize the home screen with addons like cookies home tab etc, lo limited customization is available (no widget support like in android etc)

- From just a month ago you can enjoy high res YouTube videos

BAD

- Sometimes laggy

- Browsing experience is ages behind Android and WP7, no flash support etc

- Camera is bad compared to the one on Andoird for example

- Live wallpapers are not as good as the ones on android and theres so few to choose from

- No universal search option (like on Android or BB devices)

- Gaming suck

- Development is dying or almost dead

WP7

GOOD

- Soooooo cool looking, fastest interface ever, extra intuitive and modern

- Mail app is great, very well thought trough and nice looking

- The best social networking integration, deeply into contacts

- Great gaming experience with xbox live

BAD

- Camera is only usable trough an external app, the built in is ****ty

- No direct outlook sync

- Has to be activated with MS

- No usb or wifi tethering

- No usb flash mode

- No GPS apps whatsoever, not even Google maps

- Live tiles are cool but third party apps cant really use their full potential (solved in upcoming Mango release but you'll have to wait for like a year to get it)

- No skype

- No universal search option (like on Android or BB devices), the search button is reserved for Bing search (maybe I'm wrong on this one, but as I recall you cant get to contacts so easly)

- A very long and thus very hard to use app drawer

- Cant use your own mp3 ringtones (might be wrong on this one correct me if I'm way off here)

- No real multitasking

- multitouch is implemented poorly

Android

GOOD

- Great looking interface, live wallpapers etc

- A lot of apps and games (best YouTube app ever, Skype is working fine etc.

- I just cant live without the universal search option I use all the time, so where ever you might be in the interface you are one button click away from your contacts or google search

- Has available GPS navigation software from Google maps to iGo etc.

- Great social networking apps but those options are not so deeply built in to the OS like in wp7

- USB and wifi tethering is working (not in my build for some reason but I can live without this option)

- USB flash mode working

- Multitasking

- The best camera on HD2 (a lot better than the one on the original rom)

- multitouch wirks just fine

BAD

- Battery life is bad even on phones designed for Android, let alone on ported ones :)

- No direct outlook sync ( a big minus for me, but not necessarily for everyone)

So, if you look at the pros and cons, the result is - your HD2 is the most functional with Android, then with good old WM 6.5 and at the end with WP7. WP7 needs to be polished, regardless of the quality of the HD2 port which is very close to the real thing. Mango update is coming this fall, but a lot of things are not addressed in it and MS need in my humble opinion another year to fix all missing bits...
