orcishgamer: LibreOffice Calc is just as good as Excel, if you don't think so, you probably have a Masters or better in Mathematics or haven't used it in years. PowerPoint I'll give you, but I think most uses of PowerPoint are counterproductive.
Sadly, most home buyers of Office actually do buy it for Word, they mostly don't even know about WordPad. It's mostly ignorance, honestly, and for these folks OO.org or LibreOffice work fine. You can even set them up to default save to MS formats.
lukipela: When you can show me a reason why it is better, we can have that discussion. Consumers buy office for word and outlook, businesses, which far outnumber consumers in purchases, buy Office for Excel, Access and Powerpoint.
As I said, the market is pretty clear. Claiming ignorance is the cause is ignorant.
For home buyers it is ignorant, they use no more functions in Word than exist in WordPad. Buying Office for them is a wasted expenditure. I didn't mention business use at all but since you insist on bringing it up I will note I've used OpenOffice.org in a business environment for the past 6 years, it works fine. And no, we don't waste time with PowerPoint presentations.
