All depends on:
Screen size, resolution and if 1080 does playback devise upscale (Upscal still not as good as 1080)
But For Dad, it may be more about eyesight. same as some one with class B hearing going out and Buying the BEST sound system - He will never tell the diff between it an a cheap sound system.
If you want true fidelity, retain the full size and store on a External HDD. Use computer for Playback. 1 TB drive = about 30->35 Blu-rays - Still expensive as that is about $3 per movie compared to about a Buck for a BD-R and 30 cents for a DVD±R
Face it if you want to play that blu-ray on a ipadI or II you will have to take that 13-35 gig Blu-ray file all the way 2.2 gigs.
I do this often for storing on a thumb drive for playback outside the home. Stuck a combo of 25 DVD/Blue-ray on to a 64 Gig thumdrive for play back on a laptop.
Yes There is a diff, but they were totaly watchable.
