I agree, of course every tool has some limitations. I think a set of parallell guides can also make the plunge saw much more versatile without breaking the bank. And the set i have also works well for narrow rip cuts, exept when the piece is really small to begin with. And as you say an MFT is great for repeated cuts. As another comment mentiones together with a mitre saw and some jigs i think you could replace a table saw functionally, but its probably not the most efficient way of doing some things.
