to add more answers... (sorry to be "me too"-ish)

	yes, if you can live with the keyboard.   during the newyear holidays,
	i carried NEC MobileGear 530 + NetBSD/hpcmips 1.5 when i visited my
	granma's place.  it was much light than my IBM ThinkPad, and it worked
	just fine for ssh-over-ppp-over-cellphone (and it did impress my
	family :-)  i'm so glad i carried it with me, and i would really like
	to thank all hpcmips guys.  i have tried hpcmips tree before 1.5, it
	is now so much stable than before!

	actually, console is slower for me than X + xterm (kterm - for japanese
	displays - in my case).  so i'm happier with X than with console.  it
	is a little bit tricky to click the buttons (see manpage for Xhpc).

	my recommendation is to get IBM's "1G microdrive".
