MaridAudran: Pretty helpful info; I had no idea. What's the difference between slim drives out there? From the page you linked, wherein lies the $100-dollar difference betwixt the Samsung and the HP drive?
I'm a medium-level tech-head. I don't work in IT but I enjoy doing my own upgrades and installing my own hardware into PCs. I've never done anything to a laptop before, however. How difficult will this be? I use a 3-year-old Toshiba Quosimo.
OEM - regarding hardware - usually means you don't get a huge box (it's probably just bubble-wrapped), manual, driver disc, or cables to connect it to the rest of the computer, you're supposed to have that or get from elsewhere. Neither of which isn't necessary for laptop drives (there are no cables, and Windows recognises the drive by default).
OEM - regarding software - is different, like GameRager said, you're supposed to buy it together with the basics of a computer (a motherboard and CPU, I think at least).
