BlackBerry 10 launch event as it happened 17.09 If you've had time to take all that in, what does it make you think about BlackBerry's chances? Earlier the poll was running with two-thirds saying that BB10 would return BlackBerry to dominance. Will BB10 save BlackBerry? 16.54 And now the post-launch analysis begins. First up is the Telegraph's own Willard Foxton, who thinks this is too little, too late for BlackBerry: Blackberry is a dying brand, living out its death throes mostly being used by low-value customers. Poor youths in the first world are enticed by its free BBM messaging, but people who are dissuaded from spending a penny on a text are not really the people you want using your phone, especially when they use it to advertise looting hot spots. 16.34 We've had our hands on a BlackBerry Z10 for a couple of days now. I'm finally allowed to reveal that. Matt Warman has reviewed it here. The full specs are as follows: Size: 130x65.6x9mm Screen: 4.2," 1280x768px, 356dpi Memory: 2GB RAM; 16GB Flash (hot-swappable MicroSD) Processor: Dual Core 1.5GHz Talk time: up to 11hours Camera: 8MP/1080p; 2MP/720p HDMI Port 16.27 A quick skim through Alicia Keys' recent tweets shows that she was posting from Twitter for iPhone as recently as last Sunday. She must have rediscovered her love of BlackBerry in just the last couple of days. 16.20 And that looks like it. Heins is off. Reaction to the launch, reviews and pricing all coming up next. 16.17 Keys plans to work with app developers, retailers and "other super women" as part of her new role, apparently. This isn't just a marketing thing, oh no. 16.12 And BlackBerry is announcing a new Global Creative Director, Alicia Keys, who apparently has a previously untapped talent for mobile ecosystem design. 16.10 The BlackBerry Z10 will be available tomorrow in Britain, from February 5 in Canada and from March in the US. 16.07 Oh, we haven't finished. Heins is back to sign off. I know what you're thinking? 16.06 There goes Mallick and we're into a video. Is that it or is Heins coming back? 16.03 Mallick is talking about the 70,000 apps BB10 will have at launch, including Skype, Amazon Kindle, WhatsApp and Angry Birds. It's starting to seem like he's going to name them all. 15.51 BBM now has video chat and screen sharing. To demonstrate Bhardwaj starts a video call with the London launch event where Andrew Bocking shows some of his photos, which appear on Bhardwaj's screen at the same time. After a demonstration of some other features, including the camera, Bhardwaj takes his leave and Heins brings out Martin Mallick, vice president of alliance and business development. 15.47 Next, Bhardwaj and Heins take a look at the keyboard. Bhardwaj demos gesture-based typing, which allows users to flick words from the keyboard into the message they are typing. After that they move on to BlackBerry Balance, which separates the device into personal and professional components. The company CIO can control the professional part of your BlackBerry, while you get the personal side to yourself. 15.36 Vivek Bhardwaj joins Heins on stage to demo some of the features of BB10. He's showing off Flow and Peek, which allows multi-tasking between apps and provides a hub of all the activities coming from various sources. "Love it, love it," says Heins. 15.33 Here's the moment that Heins unveiled BB10: 15.29 And after a countdown, Heins has revealed the BlackBerry Z10 and the BlackBerry Q10. Americans, please note, Heins says it's called the "zed ten," not the "zee ten." The Z10 is a rectangular touchscreen device with no front button and a textured rear backing. The Q10 is a traditional BlackBerry with a physical keyboard. 15.25 After a list of people Heins wants to thank, we've moved on to our first big announcement: RIM has changed its name to BlackBerry, which will save me a lot of typing, if nothing else. 15.21 Heins says: We aim to lead the way from mobile communications to true mobile computing. 15.19 Thorsten Heins is out, talking about how this year has been the toughest of his career but he was motivated to take the job as chief executive because of the opportunity that BlackBerry 10 represented. 15.15 It's all getting quite strange. We just met a rapper called Lil E on video, who played us his song No Sleep Til BlackBerry 10, and that was followed by a man who said he wouldn't get his hair cut until BlackBerry 10 launched. His ponytail was cut off. 15.11 Alec Saunders, the developer relations boss for RIM, is on stage talking about "his journey" talking to developers around the world about BB10. In Latin America we had a 12-year-old get up and do a pitch. 15.08 There's a video running with various luminaries from around the world talking about how much they love BlackBerry 10. 15.04 As the simultaneous BlackBerry 10 launch events get underway in New York, London, Toronto, Dubai, Johannesberg and Paris, our man on the scene, Matt Warman, send this picture from the London event. 14.45 Just yesterday, Celia Walden was complaining on this website about her husband's Twitter obsession. Here's the man now and he's got a new toy: 14.32 A good point, via Twitter. In half an hour, Apple's iOS will be the oldest mobile operating system on the market. 14.17 The journalists are starting to arrive. Here's AllThingsD's Ina Fried, arriving at the New York event: 14.12 With under an hour to go until the events begin, it's time to gauge your opinion on what BlackBerry 10 will do for RIM's fortunes.
