The upside is that this is one device with an accessory, and not two devices. It works well for both platforms and you don't have to go through the rigmarole up keeping two devices in sync. I fail to understand how you don't find this infinitely more useful than having both an ipad and an iphone. I agree the device is a little expensive, but in my mind it has clearly upstaged the Note II as the best device on the market. I can only hope this comes to Sprint.
Good points. But you may find that Asus can succeed where Motorola failed with the Atrix. With a company like Asus at the helm, I can see this platform growing to encompass a diverse ecosystem of tablets and smartphones that are interchangeable. You may eventually find that you can mix and match for the perfect combination for your needs. Of course this is entirely speculation, but I wouldn't rule Asus out. Their entry into the smartphone market is an interesting and welcome one.
