Duo Blu Ray

Should i get blu ray drive for my dell studio 15?
hi, ive brought the dell studio 1535 about a year ago now with specs of:
Windows 7 home premium
Intel Core 2 Duo T5800
3Gb DDR2 Ram
ATI Radeon mobility HD 3450
at the moment i have a CD/DVD slot drive and now planning on buying a blu ray drive from ebay. the link for that is: http://cgi.ebay.co.uk/Dell-Studio-15-17-1537-1737-BLU-RAY-DVD-Burner-K246D_W0QQitemZ390149125427QQcmdZViewItemQQptZUK_Computing_LaptopAccessories_LaptopDrives?hash=item5ad6b33533
Also recently i had my screen replaced with a full HD 1920X1080 (Im soo chuffed with it!!!) when my old screen started flickering.
the drive along with HDMI cable will be roughly £90 and was wondering if it would be worth it and also if it will be compatible with my laptop? Im generally quite good with computer so i would know how to fit the component. I would also be using it for connecting it to my 32″ HDTV and using it when traveling as im a student.
Any answers will be appreciated, thanks!
Blue Ray, especially for a computer, is a COMPLETE WASTE OF MONEY! Buy a fast DVD Burner.
