Hello all, I am looking at getting the MacBook Pro 17" in a month or so (refurb probably) and I keep looking at the difference between the standard glossy and the high definition glossy screen. I'm not big on photo editing or video stuff. I do work on some web sites, but no graphics intensive type. I may delve into the world of photography again someday, but I have an iMac 24" 2.4 ALU for that work. I digress - the question - is the hi-def screen really worth the extra $$'s? I don't have any place to go here to do an actual touch and feel and play with. Additionally, but not to take the main question off track, is the hard drive easy enough to upgrade/replace? Thanks Edit: specifying the 17" model.
