Not at all. If they had released it with all the bells and whistles it has, minus the limiter, I'd be just fine with it. I understand why they use the iOS and it was a good decision, it would just be a feature that would go un-used on mine. About the batteries: Just because you have 3s lipos does not mean 2s is now obsolete and will never be used. I've got 2 2s packs for my Mini Revo, therefore I can run it on 4s but I prefer 2s for better run times and more usable power. If I were to purchase the XO-1 and it came on 4s I'd run it and be happy with it, it should do nearly 60 MPH out of the box on 4s and that's not slow and I'm very rarely going to see much more than 50 or 60 anyway so I, personally, would run it and be happy with it. I've got 6s lipos for my other RCs and sure I'd drop them in the XO-1 just to blast up and down the street on occasion, but honestly I'd run it on 4s most of the time anyway. Heck most of the time I spend flying my plane in the Summer I'm not using any throttle and just surfing on the thermals, if I want to go fast I push the stick further and it goes faster but in reality I'm not pushing it to the absolute maximum for the entire run.
My point (again) is that it is rediculous to sell us something with these great big claims and a big price tag only to find out it goes slower than cars costing a fraction as much so you have to go buy more proprietary hardware to make it work. I'm sure there are $100 iPod touches to be had (we won't delve into how many of them are hot...) but once demand goes up prices will go up as well. Plus there's the issue of buying used stuff and the possibility of getting ripped off or buying something that's already wearing out. It is NOT just because it requires an Apple device. All things being as they are minus the limiter I would be VERY seriously contemplating buying one, I'm expecting several thousand $ this year on my tax return so I will have the means to purchase one. I wouldn't go buy an iPod touch just to use the telemetry (though the speed and temperature sensors would be convenient) but that alone would not keep me from buying it. To reference a real car I'd be VERY upset if my Mustang were limited to 50 MPH, especially since you can buy all kinds of cars for less money that will go over 50 so what's the point?
Let me re-itterate again since you don't seem to get the point. The limiter is why I personally will not purchase one. I'm not spending "only $100 for an iPod Touch if you can find one that cheap on eBay" because I don't want one, it will sit in the corner and never get used. If I spend that $100 on batteries I will absolutely run those batteries until they die, I don't have a single battery that goes un-used. It is not about Apple, it's about Traxxas/CC essentially taking our freedom from us. Never before has an RC car been sold as less than it was designed (and advertised) to be.
EDIT: So I went looking for this famed "$100 iPod Touch" and found this:

At the time of this post it's going for $76 because it's broken. All of the good ones were bringing well over $100. So really it's not "exactly like buying extra batteries except it's an Apple product and you don't like Apple so it's your problem." In fact it costs as much as several decent batteries which I'm sure I would get much more use out of than something I'd use to remove the limiter then ends up getting buried on my desk.
