I might just go with a cell phone and a 10" asus EEEPC, because the main reason why I wanted a touch was to sell my ipod mini and then replace the ipod with the touch and than download that phone thing on it so i can use it as a normal phone via wifi, but I don't know how to do that.
Download that phone thing...? Are you talking about VOIP? If so, you can only do that by jailbreaking, and even then you'll need an external mic (the ipod touch doesn't have one). And even then, of course, it will only work when you're near wifi, so it really can't replace a cell phone.
If all that is Ok with you, then go for it. IMO it's more trouble than it's worth for the limited phone functionality, but that's just me.
I would still go for the touch, if I were you. If you get the eee then you'll have that, a cell phone, and an ipod to carry around. The touch might not condense it all down to 1 device (the way an iphone would), but it will at least be only 2 devices.
I love me some simplicity.
