PLEASE, lets not eff up this thread, it's called mods you might know of, or heard of, or are doing, it's not about discussing if such a mod is required, or suggesting other notebooks to buy, those have their place but not here, here they are completely beside the point.
I'll be honest, just buy a new computer. No manufacturer is going to come out with an ATA133 SSD this late in the game. You said it yourself, its a niche market. Anyone with a notebook with ATA either is content with their notebook, or is looking to replace it, not upgrade it.
Edit: Okay,
there are some, but they are very slow. Like hard drive speeds. Might as well buy an HDD.
i'd say to mod a powerbook to make it usable it with SSD's would almost be as expensive as getting a new laptop all together.. So i dunno if there ever would be. :s

You are missing the point, it's not cheaper or more expensive or blah blah...that's like telling someone with a vintage car that wants to mod his car to buy a new one...maybe he will, maybe as in my case in computers he already has...but the point is to make a vintage piece of equipment better.
My pbook g4 is too me the perfect form factor in terms of thickness, screen size, end to end keyboard, trackpad size etc. etc. for the use that I am interested in it, that of a portable typewriter (I write a lot) and web browser, and it has a beautiful matte anti glare screen unmatched by anything right now in apple's line up. I don't want the macbook or air 13" because the hight of the screen is less than what I would require what with the stupid dvd watching ratio, nor do I like lenghty for no reason form factor and I consider the booklength powerbook much better. I doesn't matter that I have two 24" imacs, and a macbook pro 15", and an iphone or the fact that I ll be one of the first to buy the new ibook (see tablet), I want to make my vintage equipment better. Hence the thread.
Also, I have noticed that ssds currently those that do feature ata are dead slow, pity, we shall see what comes along.

Will throughput of an old ATA even benefit??? from SSD???
Of course it will, the busses were and are always much bigger than the hd/ssd tranfer rates
Plus, it's not the throughput that one aims at with such a mod, it's more so the safety of the non moving parts and the much better thermals wrt the hd.
