Dell vostro 1510 laptop any good? its specs are...?

Pretty poor really. Processor is not that good, the memory is low by today's standards , as is the hard drive. Integrated graphics never good either. I think even for that price you could find a better spec. Look for a hard drive of at least 160gb, 2gb of memory, look for any dual core processor. The machine you are looking at will find it hard to cope with even running windows Vista.
