no that gtab is classified as a tablet, and the streak as a phone, plain and simple. That'd make a the ipad a cheap giant phone, that can only use skype and no camera and shit.
As of now, I think the Galaxy Tab has been the only tablet that would even be classified as competition to the iPad. However, also as of now, I feel the Android OS isn't ready for tablet devices either. Maybe once Gingerbread is released this will change, but as of now manufacturers are mostly upscaling Android phone features on tablets. I think the main issue with the alternatives has been that while they concentrate on raising specifications and features (no doubt a good thing), the OS it runs on feels neglected and slapped together. That's the advantage the iPad has over other tablet devices- the OS. It's a modified version of the iPhone iOS, but it's modified specifically for the iPad so the overall experience is much more solid and polished than the alternatives. Spec-wise, the iPad is not much different than an iPhone, but once you actually use the device then specs become irrelevant because the OS ties everything together. App Store apps for the iPad actually do have more functionality than the iPhone/iPod Touch alternatives so it's not just upscaled iPhone apps.
Even after after about 8 months since the iPad's release, the iPad is still the tablet to beat and there haven't been alternatives worth mentioning or lackluster ones at best. Perhaps next year there will be better Android-based tablets with better OS support that will better rival the iPad. By then we'll also probably have the second iteration of the iPad with upgraded hardware, so it'll be fun to watch that play out.
