5 things that could make BlackBerry 10 a

CNN) -- All BlackBerry did Wednesday was change its corporate name, introduce two new smartphones and launch a bold new mobile operating system, BlackBerry 10, that may be the struggling company's last stab at relevance. Now it's up to consumers to render a verdict on whether BlackBerry's new offerings -- the all-touchscreen Z10 phone and the Q10, which still has a keyboard -- are worth buying over iPhones or Android devices. BlackBerry (they're now no longer known as Research in Motion) still has some work to do, and early reviews of BlackBerry 10 have been mixed. But there are some promising signs out there. Here are five reasons BlackBerry 10 may win over fans, new and old. The telephone has come a long way from the 1930s, when rotary dial models such as the one pictured here were popular, to the iPhones and BlackBerrys we carry today. Click through to see a visual history of the telephone. Alexander Graham Bell invented the liquid transmitter circa 1876. This phone box in Southwark Bridge, London, features a wall-mounted phone with separate mouthpiece and receiver from 1924. The rotary phone in this 1930s Reading, Pennsylvania, police box could be usd to summon police, ambulance or fire services at a moment's notice. Rotary dial telephones with separate mouthpieces and receivers are commonly reffered to as "candlestick" phones. This model from the mid-1930s features the rotary dial in the shaft of the telephone, rather than the base-dial models with which most people are familiar. This 1950s rotary phone features an attached mouthpiece and receiver. Men of the English Oxfordshire and Buckinghamshire Light Infantry call their loved ones after being told to prepare for duty in the Suez Canal Zone in 1956. Payphones were common up until the cell phones became popular and affordable. Some of the first push-button phones are pictured here in 1971. Franck Piccard of France talks on his mobile phone after the Mens Super G Slalom event at the 1988 Winter Olympic Games in Calgary, Alberta. This model of mobile phone was marketed by Racal-Vodac Limited of Newbury, Berkshire, England, in 1997, to serve dual roles as a mobile unit installed in a car or as a portable unit. The unit was sold with a battery charger and extension antenna for use in areas with poor reception. Cell phone manufacturers made great strides between 1997 and 2004. The Palm Treo 600 smartphone, pictured here in 2004, integrated telephone with e-mail and Internet browsing capabilities. Motorola's MPx wireless device, released in the second half of 2004, took the smartphone to a new level with Wi-Fi capabilites and a fully functional keyboard. The first generation Apple iPhone, released on June 29, 2007, had people lining up for days before and after its release. It was an advancement in the world of smartphones, incorporating a touchscreen, apps, telephone, e-mail and a host of other features. The iPhone 4S, released on October 14, 2011, expanded on the iPhone's innovations with the addition of groundbreaking retina diplay technology and SIRI. The BlackBerry Bold 9930, shown here, continues a long line of BlackBerry devices so popular they have commonly been dubbed "crackberries." They are also popular smartphones for business applications because of their fully functional keyboards and advanced e-mail capabilities. The original Motorola Droid was the thinnest of its kind at its 2011 release. Motorola's Droid Razr Maxx, on display at the 2012 International Consumer Electronics Show in Las Vegas, has a longer battery life than previous models. A visitor uses a Samsung Galaxy S III smartphone during a press day at the Samsung stand at the IFA 2012 consumer electronics trade fair on August 30, 2012 in Berlin. Last year Samsung's Galaxy S III overtook Apple's iPhone 4S to become the world's best-selling smartphone for the third quarter, according to research by Strategy Analytics. The iPhone 5 looks similar to previous models but has a larger screen and is lighter and thinner than the iPhone 4S. The phone also comes with a faster processor called the Apple A6, which connects to mobile carriers with a 4G LTE connection, making for speedier Internet browsing.

Large companies and government agencies have historically been BlackBerry's core clients. But in recent years more people have been bringing their own devices into the workplace, choosing to stick with fun, app-laden phones over devices that just offer security and IT-department approval. For BlackBerry 10, the company smartly focused on features that maximize productivity and speed. A new feature called Balance splits a BlackBerry phone into two separate devices, one for work and one for personal use. (Balance is only for customers connected to BlackBerry Enterprise Service 10 at work.) The separate profiles cordon off sensitive work information so that IT departments can control the flow of data. Personal apps, e-mails and photos are on the Personal side, so you can jump from one profile to the other. It's a way to manage both sides of your life without sacrificing privacy or security, and without dragging around two separate devices as some BlackBerry users have been doing. CNNMoney: BlackBerry's Z10 and BB10 feel a generation late Being productive requires switching between apps and tasks quickly and seamlessly. At the BlackBerry 10 launch event Wednesday morning, executives demonstrated something called BlackBerry Hub, which collects all a user's notifications in one spot. It can be accessed from anywhere on the phone with a swipe, and shows social media, calendar, BBM, e-mail and other updates (you can pick what shows up here to minimize noise). You can have up to eight apps going at once, and the feature lets users quickly switch back and forth between messaging platforms without having to open or close apps or revisit the home screen. Another popular tool, BlackBerry Messenger (BBM to its friends), got a new upgrade. The messaging app already allowed for free voice calls over Wi-Fi, but in BB10 it's adding a FaceTime-like video-chatting feature. Perhaps its coolest new trick is the ability to share your phone's screen with the person on the other end of the call (if they're also on a BlackBerry 10 device), so you can review work documents or enjoy photos together without having to e-mail or
