no file size limit and other benefits, because of ipfs, but i guess the cost here is reliability goes down as the file size goes up, and the file being popular or not, and upload/download speeds fluctuates.
i wonder if this can be updated to where we can significantly increase its reliability by adding economic incentives to it. Aside from an ads system (that's a thing i'll work on down the line that'll be an evolution to how something like google ads work), I'm thinking that you can query who holds the chunks and each has a fuel tank that basically indicates "i can guarantee I'll hold onto this/these chunks if there's gas (money) in my tank (wallet) for it" and either the uploader of the file or anybody else can see this and can send e-cash to these ipfs nodes. Basically the market decides to help significantly increase the chances of survival of the files/chunks they want on multiple ipfs nodes. There are a few issues to solve with such a system and a bunch of work to do to get things right if this is the direction, but it's interesting and opens up a market for more people and with less headaches =3
