Laptops are killing the Desktop PC at home as they already did in the office.
It is more and more common that each member of a family has his/her own laptop. Specially now that netbooks become an affordable choice for the first personal laptop of a child.
Soon home NAS will become popular as a cheap and green common storage for songs, pictures and movies accessible by all family member laptops, and also by other devices such as a HTPC or a game console connected to a TV screen. Apple Time Capsule is a nice first try for a combine NAS/Wireless router in the Mac orbit.
Except for hard-core PC gamers, not allured by PS3 or the Xbox 360, there is no clear application that justifies the slight extra performance of a desktop versus a laptop. And the increasing move of apps to the cloud, does not help the desktop cause either.
As I read from Stacey Higginbotham, of GigaOM, quoting a research group:
TBR believes the combination of a stationary display, keyboard and mouse with a mobile PC is the ideal configuration for many users.
Why would you want to buy a desktop PC for home these days?
Some are already starting to predict even the death of the laptop… see picture of device projecting a keyboard on the table (and why not a screen on a wall too)
