I liked the Mac cube concept. Overall our desktop machines are way too big. But I also think that laptops are not always the best ‘form factor’ either. I like to have my keyboard and monitor separate from the computer itself.

The iMac ‘lamp’ design and ‘PC-within-the-monitor’ designs are pretty practical as well - but your are stuck with fixed setup: you simply can’t replace the monitor or computer if it fails. You have the same problem with laptops.

But since monitors will be the biggest feature of all PCs in the future all designs will end up being built around this component anyway. And laptops and notebooks are outselling good old desktops now for several years. So the one in one machine is the future.
