But I am sold on HP laptops.
I have owned LT's for more than 10 years now and I use them hard. One of my machines (an HP) has pretty much been on and running without break for almost a year and a half with no problems. Once a month or so I shut it down to clean the fans but that's about it.
... and the fans are a perfect example of quality... HP has created easy access to the fans for cleaning purposes... Takes me less than 5 minutes to open, clean, close and be ready to run again. something that you don't get on many other machines.
The HD on my HP is also easy to remove and replace... one simple screw and the HD easily unclips from the bottom of the machine... good for people who like to interchange HD's
A laptop is a laptop but it's little things like this that make the HP stand out from others.
