Yeah, Miner... if you don't have MS Office, there isn't much point in having a computer for work-related things... but OpenOffice is an awesome alternative... not only is it's free, but also highly recommended.
Microsoft has free PPT viewers available though... http://www.microsoft.com/downloads/deta ... laylang=en
So funny story:
I was at work doing my work and some lady called saying stuff like this:
Moron Lady: Oh my god I moved some files to where some files were and then the files I think moved and I didn't save them but they were there I think and I thought i copied them and now when I open them they say they are corrupted.
ME: What ??
Moron Lady: you know I dragged some files over where the other files were but I ment to only copy them but I dragged them and then they were there but then now they say corrupted.
Me: Um ok...
So anyways the point of her nonsensical ramblings were that she had a file she needed to open and it was corrupt and MS Excel wouldn't open it.
So I went and tried Open Office and it opened perfectly. Proving that Microsoft Office sucks so much that it can't even open its own product but an Open Source Free Product created by nerds can open it perfectly fine.
