I use a laptop as my primary computer at both work and home – and I like using Linux as a Desktop OS. However the one thing that has bugged me for many years is the difficulties experienced when attaching an external monitor. Today with the release of Xorg 7.3 there is support for hotplugging external monitors. Of course this is the first iteration of the support so, as they say, the proof will be in the pudding; but I have high hopes.
On a similar note the KDE 4.0-beta2 has been released. KDE 4.0 is looking to be very promising. All I need now is for yesterdays announcement about Linux ATI drivers and my on order hp8510p will look very nice 
– who needs functionality if your desktop looks pretty?
