Living in a slum is good because it's environmentally friendly and uses less resources? He may as well argue that's it's even more environmentally friendly to die young.
I find 9.10 is working faster than 9.04. It boots faster and the interface is a little faster. The only issue I have is wxmaxima crashes constantly. I can't even do a sqrt(4); without crashing. I'm hoping patches will take care of everything soon.
Our company finally moved away from windows software RAID because of problems. One drive would fail, then while rebuilding we'd find errors on the second drive. Usually bad sectors that couldn't be read. Windows 2003 doesn't do any SMART monitoring so a drive can start failing and you'll never know until you try to read/write data to that part of the drive.
On my linux server I have smartmontools checking the drives nightly which has saved me once so far. I can't find an equivalent for windows so we've moved to hardware which can check for failing drives.
Ever since Open Office 3.0, I've been able to completely move away from MS Office 2003. I can create word documents that look exactly the same in MS Word 2003, like they do in OO 3.0. Now I can easily exchange documents between coworkers and they have no idea I'm using OO.
I work in aweful world of end-user IT for small businesses. These people are INCREDIBLY picky about how their word, excel, etc documents look. They are also incredibly slow at learning how to use office software. Switching these people from MS Office to OO is nearly impossible. People HATE HATE HATE software with a different interface. Most Office 2003 customers won't touch office 2007 for that exact reason. If OO were improved to the point that it could simulate MS Office so people could easily switch over, OO could take over. I think replacing MS Office with OO is one of the Big Steps linux needs to take to push windows off the desktop.
