Don't be fooled into thinking you have to get a centrino certified notebook to get good wireless technology. Centrino simply means that Intel products are used in three different areas of the laptop. One, Intel wireless cards are used. Two, Intel Pentium M processors are used, and three Intel GPU's(Graphics processing Units) are used. Now, it is true that as of this moment you will get the best battery life with a Centrino laptop. The next best option in terms of battery life is the new AMD Turion models. These chips are 64 bit but probably do get a little less battery life than the Centrino models but still pretty good. Also, the Intel Graphics are frankly awful. If you want to do any kind of gaming more than solitaire you will not be able to do it. So, I would definitely recommend the HP ZV6000 or its twin the Compaq R4000. You can usually find the R4000 for a little cheaper. However, shop around at stores like Office Depot or Costco and you can often find the ZV6000 for great deals. I know Office Depot often runs sales with the laptops starting at $699.00 and you can upgrade with all upgrades at 50% off versus customizing on HP's website. This can add up to big savings. For example, I ordered a pretty an HP zv6000 with the Athlon 64 3500+ processor with the 100GB hard drive and all the extras. My laptop came out to about $1350.00 on HP's website but I found out later that I could have gotten the same system at Office Depot for around $1000.00. So, it does pay to shop around. Anyway, I am very happy with my lappy and would recommend it. Just be careful if you want extreme gaming. The HP zv6000 is not designed to handle extreme gaming but pretty well handles most games that are 1 year old or older as well as the newer titles that are less graphically demanding. I'm still hoping the PCExpress card on the zv6000 will allow for future upgrades to the video graphics.
