I think it'll be interesting to see this because I'm not convinced on how well the iPad will sell. Everyone I've talked to about it says "it's just a big iPod Touch with books." Which is hard to argue against, until you point out the processing speed and that actual size of the iPad. It's too early to compare the two products though because we really don't know enough about the HP Slate. The fact that it runs Windows 7 is almost enough for me to jump on it already, but I'm hoping that it'll be able to match up (specs-wise) with the exoPC Slate linked above. It'll definitely need to have a +1 GHz processor (and the mysterious Apple A4 is enough to make it seem better than just another 1 GHz processor). I think 3GB DDR2 RAM is asking for a lot from a tablet but I'd rather see that than a 2GB RAM. The thing that Apple has over HP in this case is the "Apple Mobile Universe" as I like to call it. It's got all the apps that anyone can dream of and the OS has proven to work well (while not being able to do much). I think the iPad's level of "coolness" could be enough to outsell the HP Slate, even though the HP Slate may be better performance-wise. For any Windows product to sell well, I think Microsoft needs to adopt a sort of "App Store" that can rival the App Store of Apple. Sure, it may be copying, but hey, it's a free market economy. If Microsoft releases an SDK where the developers can do pretty much whatever they want (look at the Zune SDK) we might see some successful mobile devices coming from Windows Operating Systems. For now, however, Android and iPhone OS seem to be controlling the mobile OS market (go Windows Mobile 7!).
