To the credit of Apple, at least they have been trying to trim the resource footprint of MacOS. MS could do with following suite.
Windows 7 uses a great deal less hard drive space (gigabytes less, I believe) and RAM than Windows Vista did. My 1GB RAM, 40gb HD subnotebook Fujitsu which shipped with Vista runs MUCH better with Windows 7, and has way more free hard drive space.
over 200Mb for a driver! That's insane.
This is the vendor's fault for packaging them poorly with added "support software" and unnecessary junk ("order new cartridge!" reminders, etc.) The driver itself probably isn't more than 1mb. HP is great at making you download way more than necessary from what I've seen.
..and to the discredit of Apple, they've just disowned millions of non-Intel Apple machines with their newest OS release, while Windows 7 runs fine on my 5 year old laptop. I imagine orphaning all that hardware will go a long way to shrink the size of their OS!
