Android doesn't look vastly superior here. Neck and neck

Again, it doesn't look like Android is "vastly superior"

Let's look at some other links

So, where are the posts that say Android is "vastly superior"?

But, he got some things wrong:
- Microsoft decided against microSD support on Windows Phone 7 devices. Nope. Microsoft did not say that. It was a decision by the hardware manufacturers
- Mobile hot spot. Did Andriod support this in version 1?
- Market place. Comparing apples to chimpanzees. Android had a long time to ramp up and get apps into the store before WP7 came along. I agree that more android apps are added daily than WP7, but I have yet to look for a WP7 app that I want that I can't find, except one that I'm working on. But the same app is also missing from Android too..

He gives no reason why he says this. It's a blanket statement without any specifics to back it up.

Now for those lurkers that think Microsoft can't compete in this area

Summary:
I didn't find anything that said Android is "vastly superior" by providing accurate information. With the exception of the one Mango link I had here, I only considered links that compared shipping products.


>OMG - just google Android vs. WP7 and see the 1000's of links.

>>How is Microsoft's phone OS and software seriously lagging behind?

>Cause it stinks compared.to Android (see above 1000's of links)

>>FYI, Android is in for a nasty legal fight. Oracle has already filed suit and now a consortium including Microsoft, Apple, RIM, and others has bought Nortel patents that Android infringes on. If forsee Android devices becoming much more expensive.

>yawwwwn. Another patent fight among the computer software big-wigs. Doesn't change the fact that the Android one is better.

>I will give one thing to Microsoft though - everyone is pretty much on the same version - which is a problem with the Android devices.

>I'm really really hoping that the new Windows 8 OS and Windows 8 Phone OS are good though - like I said before I'm a windows guy and I'd rather have a windows device - but it has a long way to go to catch up.

>>>You mean WP7.0? What happened to 6.5 and such?
>>>
>>>I just think that Android (which is now activating 500,000 a day) is vastly superior. Wish it wasn't the case as I'm a windows guy - but fact is Microsoft's phone OS and software is seriously lagging behind.
