I purchased my Vostro 1500 nearly one and a half years back. It was my first laptop and my needs and expectations were purely for academic purpose (though I should say... I wanted it to run standard games)... the one aspect I like about dell is that you can configure it ..(who doesnt like choices??).
Atleast for me, I can say I am satisfied with the product. The only problem I had in the past one and half years was with the adaptor (power chord).... the adaptor developed a loose connection (could be due to my handling..) which is a recent development. I have contacted dell for a replacement. the service ..i would not call it excellent...but then is satisfactory.
About the laptop specifically, I believe it can sustain a little rough handling, though I personally handle it with care. It is compatible with netgear and linksys network instruments. Dell definitely scores over HP/compaq and acer; which were used by my brother and friend. The compaq developed heatsink problems and would shut down at high temperatures ( nothing of that sort has occured while I used the dell).
This is my first review, so I am not sure if I have covered all aspects of a laptop...but hope it is useful.. P.S : whichever laptop you buy, do make sure to check the warranty and the cost of extending it later on. Dell has quoted me Rs8000 for a one year complete cover. Have no clue if his is cheap or expensive relative to other companies !!!!
