With more data being moved to cloud services such as Amazon S3, the need for large hard drives for storage is becoming obsolete as well, being replaced by the convenience of accessing your data from anywhere on any device. Ever lose critical data or pictures from a hard drive failure? Cloud Services are built to prevent that from ever happening.

Concerned about the small screen size of your mobile device and the cramped keyboard? Try out the up-and-coming personal projectors along with the Sixth Sense Interface. Turn whatever surface/wall/table into your own 50″ monitor then control it by moving your hands and fingers in the air. It’s only a matter of time before mobile devices come with those features standard.

So will Desktops be irrelevant in 3 years? I’d say at least 5. It’s crucial to have those personal projectors and the Sixth Sense Interface perfected before that will ever happen. As soon as that does, I will happily replace my Desktop/Laptop with a single device that fits in my pocket.

Note: At this point in time I consider laptops to be the same as desktops, as majority of people who own laptops keep them in the same location, or never leave the house with them.
