Hi PPLZ,
I just wanted to check that with a $99 Apple Dev License, that we can provision multiple devices to develop/test on.
I want to go out and get a new Touch so I can compare performance on it with my 1st Gen iPhone.
I am really hoping my 1st Gen iPhone is really underperforming compared to the 3g and latest touches.
Cheers 
yes, you can add either 50 or 100 devices with the iPhone Dev Membership. (and just so you know, you shouldn’t develop games with the performance of the new iPod Touches and iPHone 3G’s in mind because there are still a lot of people out there with last year’s technology…if a game looks good on a 3G or new iTouch, it isn’t guaranteed to look good on the first gen stuff…so watch out and expect a couple of angry customers!
PS
You’ll notice some decent frame-rate improvements with the new devices…thats about it (at least from my end)
