Greeting Pfizer,
I've had my Acer Aspire 6920G for three months now and I use it mainly for development work so I got Visual Studio 2008, Visual FoxPro and SQL Server installed. Was supposed to install NeverWinter Nights 2, but I never got around it (I love AD&D games). The development tools run smoothly since the notebook is outfitted with a 2.4Ghz Core 2 processor. The OS that came with the notebook is Vista Ultimate 32 bit. If you can get the 64 bit version so much the better so the OS the can "see" the full 4GB memory. Also it has Blu-ray and a full 1080p screen. All in all I am very happy with the notebook.
The HP looks good. You have a Blu-Ray device but the screen is limited to a 1200x800 resolution and that doesn't translate to a full HD screen. I think it's 720p instead of 1080p. You can get around it by connecting to an external HD LCD though.
What will be your primary use of the notebook? If games, the Acer has a slightly better video card. For office work, both will perform quite well.
One more thing, I got my Acer for less than 90K.
Peace.
