Laptop features

Hey guys, I plan buying a HP Pavilion dv7t series in the futue, but need some help with the featues. Here what planning using it as backup for home comptuer, sufing web, downloading music and videos, tranfering all my stuff that on home computer. The current features I do know for fact I want are 17inch screen (I know it heavy, but eyes are bad), good size harddrive, and maybe blue-ray since there alot titles I like that are on the format. Here a link to the laptop and there two options for a base configuration and recommended configuration right hand side screen, also did not want to make list all options. When you make a list of features, make sure you list if base or recommended configuration.

This is the one I wanted to buy las xmas, but didn't because I couldn't sell my old one. My old one was only smaller.

You have to decide for how long you want to use it.
The longer the better it has to be.

Base configuration for 3-5 years, it will still be good for longer
CPU: Intel(R) Core(TM)2 Duo Processor P7450 (2.13GHz) +100$
uses 29% less energy, is 6+% faster

Memory: 2GB is good enough, but I think you will need 4GB+50$ in the future to run smoothly

HDD: 500GB 5400RPM SATA Hard Drive with HP ProtectSmart Hard Drive Protection +50$
It is good point to sell it later.

CD/DVD/Blue-ray: Blu-Ray ROM with SuperMulti DVD+/-R/RW Double Layer +150$
it can only read Blue-ray, not burn!
I don't think you need to burn Blue-ray,....they don't sell burners anymore, it would have costed +250$

= max +350$ = total 1149.99$ BUY THIS
------------------------
Recommended configuration, same configuration:
HDD: 500GB 5400RPM SATA Hard Drive with HP ProtectSmart Hard Drive Protection +50$

CD/DVD/Blue-ray: Blu-Ray ROM with SuperMulti DVD+/-R/RW Double Layer +150$

= max +200$ = total 1253.99$
