World's first Laptop...

Toshiba launched the Toshiba T1100 in 1985, and has subsequently described it as "the world's first mass-market laptop computer". It did not have a hard drive, and ran entirely from floppy disks. The CPU was a 4.77 MHz Intel 80C88, a variation of the popular Intel 8088, and the display was a monochrome, text-only 640x200 LCD. It was followed in 1987 by the T1000 and T1200. Although limited floppy-based DOS machines, with the operating system stored in ROM, the Toshiba models were small and light enough to be carried in a backpack, and could be run from lead-acid batteries. They also introduced the now-standard "resume" feature to DOS-based machines: the computer could be paused between sessions without having to be restarted each time.

World's first android phone...

The world’s first Android phone was the HTC Dream – it came to the market in October 2008 as the T-Mobile G1 in the USA and, when signing a two-year service agreement, sold for $179.Dream was the first commercially released device to use the Linux-based Android operating system, which was purchased and further developed by Google and the Open Handset Alliance to create an open competitor to other major smartphone platforms of the time, such as Symbian operating system, BlackBerry OS, and iOS.

World's first Operating system...

Well, there are many school of thoughts about who was the first to create the first operating system. 

They ranged from: 

1) DOS (actually QDOS 0.10 - Quick and Dirty Operating System) originally by Seattle Computer (later acquired by M$). 
2) CP/M, for Control Processor Monitor (was considered the first operating system for a personal computer) by Gary Kildall of the Naval Postgraduate School in Monterey, California 
3) IBM 

Many argue it was CP/M was the first. The debates continues till today. 

Worlds first Television set...

John Logie Baird FRSE  14 August 1888 – 14 June 1946) was a Scottish engineer, innovator and inventor of the world's first mechanical television; the first publicly demonstrated colour television system; and the first purely electronic colour television picture tube. Baird's early technological successes and his role in the practical introduction of broadcast television for home entertainment have earned him a prominent place in television's history.

World's first ATM...

It might just be the best idea to come to a man in the bathtub since Archimedes' time. While taking a soak, inventor John Shepherd-Barron devised what is hailed as the world's first automatic teller machine, although his claim to the title is a matter of dispute . He pitched the device to the British bank Barclay. It accepted immediately, and the first model was built and installed in London in 1967. Though the machine used PIN (personal identification number) codes, a concept Shepherd-Barron also claims to have invented, it was dependent on checks impregnated with the (slightly) radioactive isotope carbon 14 to initiate a withdrawal, as the magnetic coding for ATM cards had not yet been developed. One other difference from its ubiquitous modern counterpart: it didn't charge a fee.

World's first camera with film(paper films)...

The use of photographic film was pioneered by George Eastman, who started manufacturing paper film in 1885 before switching to celluloid in 1889. His first camera, which he called the "Kodak," was first offered for sale in 1888. It was a very simple box camera with a fixed-focus lens and single shutter speed, which along with its relatively low price appealed to the average consumer. The Kodak came pre-loaded with enough film for 100 exposures and needed to be sent back to the factory for processing and reloading when the roll was finished. By the end of the 19th century Eastman had expanded his lineup to several models including both box and folding cameras.
