Thats a nice price for that laptop. Regarding OS disks, the last one I got was with a Dell laptop several years back, since then I've purchased 5 laptops for family all different brands and none of them have come with a OS disc.
The absolute worst was the Compaq, whose own Restore Disc creation software refused to identify the cd/dvd drive in the laptop (brand new!!!!). Any number of times I tried with driver updates or anything else didnt work and tech support was a complete FAIL. They asked us to pay money to get them to ship us restore discs. Hell no! I took a chance and haven't had the need to do a restore on it for 3 years and its starting to fail slowly anyway. But never again!
Sony was ok, the software did a decent job of telling us what was needed and did a quick job of it.
Toshiba was the best, the restore process (I had to use it once cos of a virus) was super quick and easy and the machine was back to new after that. Least bloatware among the lot as well if I remember correctly.
