Estimate: 2.5M Windows Phone 7 Shipments in Q1

HTC and Samsung makes a killing selling mobile phones, mainly thanks to Android.
Nokia, unfortunately, is lagging, but not out of the picture.
But because of the sheer volume of these three phones seller, can the future be good for Windows 7 Phone like HTC, Samsung and, soon, Nokia, offers WP7 handsets.
The iPhone is not struggling.
It looks as if the market gains of these players came mostly at the expense of RIM's BlackBerry devices.
HTC (Check if model is pictured) saw global sales of smartphones jump by 229.6 percent in the first quarter of 2011 to 8,900,000 units, from only 2.7 million in the year ago quarter, giving it a market share of 8.9 per cent against 4.9 percent a year ago, according to figures released this afternoon by IDC.
The market share fell dramatically, however, to 24.3 percent in the first quarter from 38.8 percent a year earlier.
This gives even more reason for Nokia to abandon its Symbian operating system Windows 7 Phone, although Nokia's running WP7 will not be available until October at the earliest.
Earlier this week, Nokia announced Chairman Jorma Ollila, he will leave the company next year.
While some readers of this blog is quick to connect the words with Windows 7 Phone FAIL, I think the long-term outlook for the OS good.
Despite the nagging, perhaps exasperating, problems with installing NoDo update, I've oftentimes said that I find WP7 competitive with Android OS and Apple the IOS.
It's user interface is easy to navigate, and it's developer community is growing at a healthy pace.
And I think that Microsoft will have a strong Nokia bang when the devices come to market.
IDC seems to agree with me.
Other highlights from the survey: Apple iPhone sales grew 114.4 percent to 18.7 million units, from 8.7 million the year before, for a market share of 18.7 percent from 15.7 percent.
Research In Motion sales of 13.9 million BlackBerry smartphones in Q1, an 31.1 percent increase from the year ago quarter.
Like Nokia, though, the BlackBerry's market share also fell, by 13.9 percent from 19.1 percent a year earlier.
Overall, jumped global smartphone sales 79.7 per cent in 1 quarter to 99.6 million units from 55.4 million years ago, as consumers trade in mobile phones for the more feature-rich smartphones at a rapid pace.
