> this sound really spoiled.
Spoiled in that I can afford to pay for office when I need it for a moneymaking business, sure I guess. But it is not being spoiled to judge an alternative by the same metrics as the incumbent, if it doesn't meet my requirements it doesn't matter whether it's paid or free.
> Expectations are very important for perceived usability,
I grant you that the UI is laid out differently and things are done in a different matter, which isn't intrinsically worse. But in this case I argue that it is.
For example, I have a set of x-y coordinates that I want to plot. I accidentally do not select all of them when creating the chart. Where do I now go in order to extend the selection?? Where do I go if I forgot to add the column headings to the selection? New users can certainly learn these things with enough head bashings, but it can certainly be more accessible.
Why does the UI seeming keep disabling my trackpad scrolling as I focus on chart elements versus the sheet as a whole? Why does it come to a glacial crawl when working with more than a few dozen points? Where is the option to disable snap-to-column/row when panning?

High praise. Though I agree with you. If you have different requirements, especially less of them, then I'm sure that you can do manage just fine without excel.
