> However, the desktop in general is just much better than alternatives for certain things. It will take on a smaller less 'generally used for everything' type of role, but I can't see it dying in the forseeable future.
The sales of desktop computers, whether they are on top of or under the desk, are declining. The usage of desktop computers is also declining as the tasks done in the past on desktops, such as web browsing and email, are being done on phones, tablets or other smaller devices. Most of this is because all recent desktop computers are 'good enough' and won't need replacement for many years, and most mobile devices are 'good enough' to replace their usage.
Declining or dying does not indicate complete elimination, as indicated by 'lingering'.
