Hey there, Mishima! I often use a similar nick to yours on other parts of the 'net :O
Recently got my own Dell Vostro 1500-3, you really can't get a better value laptop for the same price.
There are two issues to note, however. Firstly, there is the known fault with the centrino santa rosa (?) platform which results in a very noisy headphone socket, however I gather this is unavoidable for all laptops based on this platform (and expressport sound cards are easily enough acquired). Secondly, it is by no means light, but as far as I can tell you can't really avoid this and the weight is actually nice for when it's in use.
Despite the above two issues, I would still recommend the system. The 1440x900 monitor is very nice, and with a 9-cell battery, it just keeps on going
