Last week, four mobile phone makers around the world came up with a series of devices that run under Microsoft's new Windows Phone 7 operating system, and HTC was one of them. Moreover, the company unveiled the most Windows Phone 7 devices

, namely 5 of them, including the HTC HD7, 7 Pro, 7 Mozart, 7 Surround, and 7 Trophy.

We already had the chances to take a look at all these mobile phones, and now HTC offers us some more of them through a series of video previews published for each of them.

The new video presentations were published on the handset vendor's YouTube channel a few days ago, offering some info on what each handset comes to the market with, as well as a glimpse at how each of them looks on the outside.

The most notable of them are, of course, the HTC HD7, which should arrive on shelves with a large 4.3-inch touchscreen display, the largest in on the market, and the HTC 7 Pro, which comes with a sliding-QWERTY keyboard, in a form factor similar with that of HTC's Touch Pro2.

Here's how the video for this device is described: “Introducing the HTC 7 Pro - the Windows Phone 7 with a dedicated QWERTY and perfectly angled display. Take a quick look at what you can do with this smartphone that helps you get things done fast.”

As for HTC HD7, it should prove the most appealing Windows Phone 7 device where brought to shelves in Europe later this month (the HTC 7 Pro won't land until early 2011), or in the US on November 8th.

However, the other three WP7 handsets that HTC announced officially last week are as appealing as they can be too, since they all pack large displays, complemented by great multimedia features.

All in all, HTC managed to come up with a quite appealing Windows Phone 7 lineup, aimed at various market segments, and able to offer a great mobile experience to users.

In all fairness, it still remains to be seen how well would these devices perform on the market but, based on what one can see in the videos below, we are confident that they would do well.
