Desktops / Laptops / Tablets / Smartphones
The other day I was reading this article - iPad: The PC Killer. It is interesting to see that the sales of PC have dipped almost for the first time in last decade or so and those of tablets and mobile phones are fast catching up. There are other similar articles -

How will this shape up? What devices will we have in future? Here's my opinion on this trend.
I would look at it from the different types of consumers. There are essentially 3 main types of users of such device: Individual/Home users, Business Users and Developers. Needless to say developers will continue to need to devices like desktops and laptops as they need bigger screens to design and program the applications, still need keyboard and mouse devices instead of touch /gesture (which compromises speedy and accuracy) and would typically need large local storage (large hard disk).
Individual/Home users would need some device to access their emails, photos, watch videos, play games and chat with friends. While they can easily make do with external hard drives and you get 1 TB+ disks at very low cost already, lot of home user's data will also end up on cloud (Sky drive or iCloud or anything such infrastructure). Since home users will also want mobility, a tablet fits very well for their needs. Combine this along with a phone and they are done. While smart phones allow lot of the other things also, but personally I believe tablets will win over due to better real estate while still providing good mobility and phones will eventually go back to being mostly phones only. You may argue that tablets will possible also start providing audio/video call features, but a pocket sized phone device still is really more mobile than tablet. My take is that individual/home users will slowly move away from desktops/laptops and switch to tablets.
Business users at work mostly deal with emails, viewing dashboards, or making presentations or working with documents/excels sheets, managing approvals etc. Most of these are again easily serviced by a tablet, however with the caveat that the tablet is connected to official network. With more and more focus on bring your own device to work, this will soon become a reality and business users will also find working with tablets more convenient. In few cases where they need to be high productive like writing papers/documents etc., they can also work with add-on keyboards to tablets and rest of the time, be as mobile as they need to be with their tablets.
Some home users will be business users and some will be developers and some with just pure home users, so it is a no brainer that tablets will eventually will the battle. The desktops and laptops will be left for those geeky people sitting in their cubicles and buried deep into their programming.
There are multiple vendors with iPad the clear winner as of today. However there is a new kid on the block: Windows 8 and there could be reasons for Windows 8 giving iPad a run for its money.http://www.itbusinessedge.com/slideshows/show.aspx?c=95196. Which of these eventually wins or both survive, only time will tell, but tablets are here to stay for sure.
In addition to this smart phones and tablets have also made touch and basic gestures on these devices as almost first citizens. Touch and gestures have taken away the need for mouse and onscreen virtual keyboards have made hardware keyboards redundant. For high productivity needs of programming intensive work, keyboard and mouse will still continue to be relevant. Alongside there is also evolution of touch less devices like Microsoft Kinect and Sixth Sense like technologies. These technologies will play an important role in the way we will be interacting with future devices.
