I don't understand how people can be so excited by features that android and ios already have.
There will be a slew of Siri vs. Cortana vids popping up after Monday. We'll see how things stack up.
Yes, Android and IOS have had many of these features, but one thing people need to understand is that those platforms are a LOT more mature than Windows Phone. Now, taking that into account and seeing how far WP has come, it's pretty exciting.
Yes, Android grew at a staggering pace and things were added all the time, however, if you put 2 Galaxy S4's side by side after they have been used for a month and do similar tasks on them, they will all react and perform differently. This is because users will install different apps and activate different features which will hit the performance of the device. Not to mention if you put differing manufactures devices together, you will get vastly differing performances.
Whereas, Windows Phone will perform smoothly and reliably across all devices. Sure, app launch speeds will differ because of hardware, but once loaded, performance will be on-par with one another and the general feel of the UI will always be smooth.
This is one of the many reasons why I dumped Android in favor of Windows Phone.
Now, just because I work for Microsoft does not mean that I am drinking the cool-aid, I started here with a Samsung Galaxy Note and was REALLY popular and active on Android Forums here (was even a moderator), but after having a chance to play with and use WP8 before launch and seeing what it could do, it really was a better fit for my lifestyle and usage. Not to mention, to me, beautiful. I have not regretted it since.
Sorry this got so long winded. I just stand firmly behind our products and brands. If asked, I will tell you the good and bad, because it's not always good. I'll tell you truthfully if a product/service we have isn't up to par, but I will tell the other side of the coin too.
