I bought  the HP Pavilion thin line because it took up less space on my desk.  It was difficult to use and was not what I was expecting.  In less than two years, of course after the warrenty was out I smelled a burning scent, and it shut down.  I would let the PC cool and continue with my work.  It would over heat and I would have to shut it down again, sometimes loosing my data.  Sometimes it would just shut down.  My local PC service said it would be over $200 to replace the electrical board, so I just bought a new hard drive.  I was very dissapointed in the performance and cost to replace...
