There is a difference between the two. iChat requires that you keep the app open to receive IMs, video, and voice call. On the other hand, FaceTime uses push notifications and there is no log in required (beyond the initial setup) and no buddy list to manage. Also FaceTime is not chat service.
It seems that Apple wants to market FaceTime as a device service for Macs and iDevices and they want it to be built into Mac OS like they did with iOS (this is late for Snow Leopard though).
Why not roll them all into one? One app that you can make yourself available offline/online, according to your preferences. Merge your Buddy List and Contacts into one list. If someone has FaceTime, you click the video icon. If not, you start a text chat.
I see no reason why these shouldn't be merged. It totally fails the "what should I tell my mom" test. Well mom, if you want to get ahold of me on my phone, use FaceTime. Well, except if I'm at my computer, cuz actually it'll ring there too. But if you wanna IM me, check to see if I'm signed into AIM. But if it's short, just text me and I'll receive it on my phone.
Apple is renown for its integration, simplicity and parsing of extraneous things. This is an enormous exception to that ethos.
