[plug] Which brand of laptop?

[w0018749]

I am buying a new laptop and I want to know: What brand of
computers are the best?  This question probably has many
answers so just a link to another discussion somewhere would
be enough - or even a list of brands to avoid.

These are the things I need on this laptop:
1- big enough hard drive to have both linux and windows
2- keyboard with a number pad at the right (if possible)
3- DVD player and cd burner
4- wireless internet
5- I also need a stress-free installation process - I have
had several attempts of installing linux and not many
successes

I plan to install ubunta (spelling?) as I heard it can be
configured for wireless.

I have been using linux for about a year on an old IBM
"thinkpad" R52(?) laptop with 10Gb of memory.  It works good
but its not big enough to run windows which I need from time
to time for programs sent from Uni.  I have a DEL desktop
but I am not so sure about that company.  If usb sticks are
an indicator TOSHIBA looks good since you can fit two side
by side in two adjacent ports and in the shell it does not
have spaces in the key directory (TOSHIBA).
