Sorry about the dead HP, but congratulation on being able to dump
Microsoft.  I've always kept it on mine (doing a dual-boot) just because
when I have a hardware problem and have to call up tech support, they
want me to run MS stuff for testing and if I only have Linux, they say
they "don't support Linux" and so I then own the hardware problem.

I currently have 21 days uptime on my notebook, a four-plus-year-old
Dell Inspiron 600m.  I've often had more than double that uptime.  I
bought it with a half gig video RAM (not shared), a half gig of system
RAM, and a 60M HD, the latter two of which I upgraded to 2G RAM and 320G HD.

It's solid.  Yes, I've had about one hardware problem a year, but got an
extended warranty, so I just call up their tech support, walk through
the problem with them (they've always been reasonable or better than
reasonable), and someone comes to the house, generally the next day and
fixes it in a half hour.

At the end of the fourth year the extended warranty could no longer be
renewed.  I called them up again because, with all the typing I do, I
wore the letters of several of the keys.  Other than that, the keyboard
was fine.  But they replaced it.  In fact, with some confusion over
whether I was going to replace it myself of someone else was to come
out, I wound up with a spare new keyboard.  Similarly, the touchpad was
worn down.  They replaced that too.  The hardware tech also wanted to
give me a new screen, but I told him-- at least twice-- that, no, I
really didn't need it.  The CD/DVD R/W was questionable, so they
replaced that too.  While the tech was here, I had him take out and blow
out the fan (which was really clogged up).  With the RAM and HD upgrades
I did myself, I pretty much have a new machine.  I had one other Dell
laptop before this, corporate supplied, and I was happy with that one too.

This 600m is cool because it has a swappable bay.  That is, I press a
button on the side and the CD/DVD drive slides out and I can put a
second battery or a floppy drive in its place.  With the second battery
in it, I've run this machine for more than seven (7) hours unplugged.

The Intel wireless (b/g) has always worked fine.  The only headache
there was getting it correctly right on Linux initially.  No problems at
all attributable to hardware.

This Dell sort of has the same issue.  I fixed this by spending $3 on a
TV tray a little wider than the laptop, big enough so that the DVD tray
can pop out enough to insert/remove the disks, but with lips low enough
lips to not get in the way of plugging in USB sticks and other stuff.
The little bit of extra space is a handy place for pens and pencils and
sharpies, scraps of paper and USB sticks.

I ran opensuse for the first four years on this machine, then switched
over to centos.  Way too many folks on the opensuse lists with severe
ego/attitude problems.  Ubuntu isn't on my OS horizon simply because I
don't want to type "sudo" fifty or a hundred times a day.  And I prefer
rpm/yum to other package management systems.  It's what my job calls for
and I don't have a choice in that.


The (relatively) old programming maxim, "Fast, good, cheap... pick two,"
generally applies to buying a laptop too.

Hope you find something which works well for you.
