As posted in another topic recently last week, the main drawback of the HPDV1000 is a much narrower viewing angle for the 14" widescreen LCD (which is only on a couple of models) versus the very good viewing angle (viewing from the LCD from an angle not head on) of a 15.4" widescreen which is heavily used on various computer manufacturer notebooks.
The main reason people buy the 14" widescreen is that they want to stay under 6 pounds of weight (about 5.4 pounds in the case of the HPDV1000) versus the 6.5 pound weight or up to 7 pounds in most cases for 15.4" widescreen notebooks (which use a Pentium M Centrino cpu -- other cpus would drive the notebook weight even up to 8 pounds or more).
I like the 15.4" widescreen LCD for my use very much (moving around the house mainly using wi-fi all the time unplugged). It will fit in many notebook backpacks and the 15.4" widescreen and keyboard (more room for keys and even speakers to the side due to the wider LCD) is great for everyday use.
Note also that square internet web pages can be unacceptable small in my opinion on the 14" widescreen which will make a square image of smaller than 13" -- the square image on a 15.4" widescreen in these cases is about 14" which is acceptable and worth that tradeoff to get widescreen DVD's and additional width using excel and writing computer code lines on a widescreen (versus buying a square 15" LCD).
The only main drawback for the HPDV4000/HPDV1000 at this point is that it does not offer a dedicated video card option. The Dell 6000 has the 128mb dedicated video option and I highly recommend that for everyday use of a notebook computer (if used as a 2nd travel computer and only for internet use and e-mail (but not video streaming alot) integrated video is ok.
Note that my Compaq X1000/HPZT3000 15.4" notebook predecessor to the HPDV4000 series (and sister Compaq model --purchased in May 2004) had an ATI 9200 dedicated video option so that is why I bought that notebook and I still use that happily for my use today.
I need some help on deciding which model to purchase. The Dv1000, or the Dv4000. They are basically the same computer with the exception of the screen size. Any help on which one I should buy would be appreciated.
