The laptop I dream of, unfortunately, still doesn't exist... it should:

have OSX as the main Operating System
have a multi-core CPU and other state-of-the-art hardware to be a reasonably fast machine in different working conditions
have lot of out-of-the-box connectivity options, wifi, gigabit ethernet, bluetooth, etc.
be energy-savvy, a lot of noteboooks really work well only when plugged to the AC. I want to do a Roma-Milano in train and still be working at Firenze
be lightweight enough to be carried on, especially on Monday mornings

... so what? This is very similar to a Macbook! But I also need...

a fast virtualization approach: I want to install in OSX different images and work with different operating systems and network configurations at a reasonable speed. In my daily work I absolutely need Solaris and Linux, with Windows coming as a nice to have. Multiboot is not an option, I definitely prefer a true virtual approach.

Basically, I am ranting because I think the Macbook is now the most appealing machine (although quite expensive), but is lacking a virtual machine software, at least for me, to be a strong-buy. Microsoft Virtual PC is slow as hell and impracticable for serious use, and I don't know of other OSX Virtual machines which really work. Now the macs have Intel processors, so this should be only a matter of time...

Let's see what happens in the next few months! In the meanwhile, I just signed this petition...
