I was wondering what you were on about when you started talking about spec like a ferrari for a laptop!
In my own experience I've found Toshiba to be the best, Dell is very hit and miss to be honest (NOI to Acer/whoever actually makes them). I use a Dell Latitude D600 at work and haven't had any problems with it at all, very happy with it, but there's D610s around that all had to have something replaced on them.
My brother got a Dell Inspiron 1100 a year or two ago and has had various problems with it, and I've heard numerous others with Dell laptop problems too.
Stay away from the HP laptops methinks, had one at work running Windows, and it had to be reinstalled every few months to stop it crashing all the time. They were the standard laptop for a while here but they had to get rid of them (in favour of the Dells) 'cos they were too troublesome. That and they weighed half a tonne!
There is the Intel based Apple laptops but I guess they probably won't run Solaris for you, that processor may not be supported, so maybe thats not an option.
Feicers put PGP on my laptop, which means now it takes about 20 minutes from startup to the time I can get to my email!!
