The only similarity to the iPad I see is that it's a large screen that you touch to interact with. The nav bar, multitasking, notifications, widgets, theme, and app styles are all pretty unique. Well, the Gmail app looks pretty similar to the iPad's, but I'm assuming they're not going to change much there since it's their own product.
It does look like it needs a bit more designer influence and less engineers doing UI work though. Polish has always been the strong point of Apple products, and that's really the area I'd like to see Google play catch-up on.
That being said, I'm pretty excited for the future of Tablet devices. The iPhone, Android, and WP7 handsets wouldn't be half the products they are today without the competition from one another, so Android Tablets can only mean good things for this market.
