I'm using A45V. Very happy with it. Only complaint is the power jack, not as easy to insert as other notebooks i've used. I've used 3 types of HP notebooks from work and a few Dell laptops for personal use.

Battery life pretty decent in when in battery saving mode IMHO. Sound system not bad but must be elevated on a cooler otherwise will be muffled slightly.

The icecool palm rest generally works but does get slightly warm after a longer usage time. However will not be as warm as Dell inspiron or HP elitebook (sorry can't remember the model numbers).
