I'm with britechguy, I don't see much point in burning to optical media. The only thing that really makes any sense is pictures, since they aren't going to change. Even then there have been issues with how long optical disks hold information.
As far as watching. Like DVDs you'll need software to play Bluray disks. Bluray incorporates HDCP. With HDCP if anything in the chain is not HDCP compliant you may have anything from nothing to degraded play back. I mention this, not to ward you off, only to inform you.
Play back experience can vary widely. I copy all of my disks to hard drive and play them with PowerDVD. If you're going to purchase PowerDVD, they release new versions in April, so you may want to wait. Some disks require you use an on screen control, other work just like DVDs where you click the menu items you want. The advanced features that you would get on a dedicated Bluray player aren't as easily accessed. For just watching a PC works fine.
Unless you have a real need for an optical drive you might want to just wait until you need one and purchase a USB 3 external. Other than movies there is no real need for an optical drive these days.
