Microsoft users, it's time to switch (kissflow.com)

I can only comment about MS office as I use it everyday at my office.

I can not think how Google's spreadsheet can replace Excel.

I have some thousands of rows on a single sheet and a spotty internet connection. If Google introduces a native, offline app, then i might switch.

I'm trying to understand who would upvote this. It's not a "good article" or a "good blog post" - it's just a comparison of product names along with some probably-unknown-to-you person giving you advice. I can find that all day, every day on any number of crap sites. Why does this has so much as a single upvote?

The article (or rather, elevator pitch) is somewhat lacking. Does it only claim "newer = better", or did I miss something?

That's not thinly vialed self promotion. I notice the only thrid party app happens to be the same domain as yours. You could have done a little digging and at least come up with a few alternatives not even in the same category besides yours.
