Kill off the laptop, it's turning into a thin desktop, with overpowered internals and underperforming duration. Portability just means lugging it from one place to another, with use inbetween giving a very limited experience.
What we're really looking for here is a central server (lolcloud) to handle applications we want on all of our devices (office package for example) not putting performance/latency dependent applications on there (which seems to be the fancy of many a tech blogger).
Personally, I would want something on a netbook/slightly bigger scale than having the ever expanding screen of a laptop for 'portable' work. With desktops for when the real business needs to get done.
Hell, at home when working, I connect the laptop to the desktop screen and peripherals to get anything done. Something that could be done using a) the desktop with shared applications from the cloud or b) the much more portalable netbook.
Laptops have so much bloat these days, I don't need a trackpad (a small trackball would be much nicer), a dvd drive (easiliy replaceable by the 'cloud' I keep having rammed down my throat)
