Consider a small form factor PC, they are small enough to carry home and you
get all the power of a desktop. The only disadvantage is that you can't use
them at an airport :-)

Correct, if you need a parallel port just look on ebay for a low-cost PCMCIA
parallel port card (don't buy a USB to Parallel port cable since they do not
work with dongles and apparently download cables). Serial ports are no
problem, I bought a 7 USB to serial port cable and it works perfectly ( I
use it with Teraterm to connect to my prototype board).

Definitely, most EDA companies do not yet support Vista and if you don't
care about wobbly windows then stick with XP. As suggested by Andy I would
also recommend you set-up a dual boot with Linux. If you do this then I
would recommend using Redhat or one of its clones like CentOS 4.4 (not 5).
Linux is a great EDA environment although for some reason some EDA companies
still like to charge extra for their Linux version. I would also suggest you
keep your XP installation since you might nullify your warranty (completely
brain-dead I know).

If you want more screen area go for a single 24" (1920*1200) display since
they are absolutely great. I used to have two 19" screens and I get tell you
that a single 24" screen works much much better. Also most EDA tools require
large high-res screens, look at the number of windows in Modelsim or HDL
designer, you simply can not use them on anything less than 1280*1024 unless
you are one of those persons that can watch and enjoy a video on your mobile
(cell phone) :-)

Go for 4Gbyte, this will make your P&R run a lot faster. Yes you can only
use 3.2GByte under XP but even the extra 1.2Gbyte will make a difference.

According to an English PC magazine both Rock and PCnextday (zoostorm) came
out as one of the fastest laptops in their price class:

With the current speed of development I would say a year is just about long
enough before it is time to pass on your laptop to your kids or family
member :-)
