Last yearâ€™s party was controversial.
The last Windows Phone 7 Launch party last year ended up being pretty controversial, with Microsoft being accused of overconfidence in symbolically burying Blackberry and iPhone effigies.
It is safe to say todayâ€™s event will likely be more sedate, with more Mangoritas being served.
This yearâ€™s party appears a lot more sedate.
It is however certain that the Windows phone 7 team deserve all the partying the can cram into today, and we hope on Monday they get right back to adding tethering to Windows Phone 7.
