I don't know much about Acer
No floppy drive
I wouldn't worry to much about the video card unless you are into gaming or run a lot of graphics programs.
Maybe look into a TV tuner that works similar to Tivo so you can save or record tv programs and put them on a disc.
If you copy a lot of DVD's and/or CD's , maybe dual optical drives.
Go to techbargains, Dell usually post some good deals available through the site. Usually on Weds.
