Motorola DynaTAX 8000X (1984): The first handheld cellular phone. Loved by yuppies and people with large shoulder pads who would yell "buy... sell" into it. It weighed more than a house and didn't even do picture messaging.
Nokia 1011 (1992): One of the first phones to use the new GSM phone system. Because the signal was digitally encoded, random snoopers with radio receivers were no longer able to listen in to private conversations.
Motorola StarTac (1997): "Scotty. Beam me up" was what sci-fi fans would have said, had their battery lasted long enough. This Star Trek tribute mobile phone was one of the first to pose the eternal handset dilemma – to flip or not to flip.
Nokia 5110 (1998): Arguably the first 'fashion' phone. Interchangeable multi-coloured fascias allowed users to customise their handsets. Helped by the hugely addictive game 'snake', it became one of the most popular mobiles ever.
Motorola MPx200 (2002): One of the first phones with Windows Smartphone OS. Users could email, instant message and install applications. But Microsoft didn't maintain its innovation and CEO Steve Balmer said in 2009: "We screwed up with Windows Mobile."
Motorola A920 (2003): Forget boring old speech, the arrival of 3G data speeds meant a brave new world of video calling. Unfortunately nobody really wanted to see or be seen while chatting on their mobile. To this day the feature remains hugely underused.
Blackberry 6210 (2003): Posh handset, mainly used by business people. However, it introduced the concept of mobile email addiction. 'Crackberry' addicts would click their way through messages wherever they went. We all do it now. It is still very rude.
Nokia N70 (2005): Back when installing apps was still the preserve of geeks, Nokia sneaked this smartphone into the hands of regular folk by making it look like a normal phone. It was, however, capable of running sophisticated games and programmes.
Apple iPhone (2007): They called it the 'god device' and it turned the mobile world upside down. It's not perfect. Users complain about battery life and the fact it can't run multiple applications. But many owners still go to bed cuddling their iPhone.
HTC: Not strictly a single handset, but a mobile operating system from Google. There are now more than 18 devices running Android. Fans like its open-source system that allows anyone to develop software without going through an Apple-style vetting process.
Nexus One (2010): Google's own-brand smartphone was widely billed as a potential iPhone killer but time will tell whether it lives up to the hype. The touchscreen phone runs Google's Android operating system.
