> Me, being skeptical of the theory, I still choose to concatenate (I think it's clearly the way to go)

I have to agree with you. Seeing how my non techy friends use their not high end mobiles, I've decided to go down that road too.

Some of my friends clear cache very frequently, their main point is that images take too much room and this slows device down. Knowing that this is not the case and cheap phones just are slow, they pretty much defeat the whole purpose of cache. I've found that the only way to make web faster for them is to concatenate everything.
