The Tab is no worse than the iPad. They are both overgrown versions of their respective phones.

As an side (in response to an earlier post) few people I know hate Apple. Its Apple's fanboys and acolytes (and the accompanying detachment from objective/rational thought) that they actually dislike. ...
Your post is an excellent example of why some anti-Apple (or anti-Apple fans) people think they are being rational when in fact they are some of most irrational people you'll find. The iPad has plenty of apps that are custom made to take the full advantage of the larger display size, which is the whole point of a tablet. Sure it's largely based on the iPhone OS, but Apple made changes and support the OS for the tablet.
On the other hand, Galaxy Tab's Froyo is literally overgrown phone OS with a very few apps that are made to take advantage of the screen size, mainly because the the company who made the OS themselves said they don't want to support it for the tablet form factor. Yet here you're trying to make them look like peas out of the same pod.
When the first iPhone came out, I'm pretty sure something like this went down between friends:
Potential iPhone buyer: "Wow, the new iPhone feels really smooth and UI is very intuitive, I'll buy it."
anti-Apple(fan): "You're irrational and deluded. Let me tell you why. Check the list of features: Windows Mobile phone has an external memory slot and a rechargeable battery, Windows Mobile has copy&past, Windows Mobile allows you to use the stylus which is much more accurate."
anti-Apple(fan): "...See what I mean? Windows Mobile has so many more features than the iPhone. You're detached from objective rational thought if you buy the iPhone. It's all bling."
A potential iPhone buyer: "But the iPhone just looks and feels better and it's so much easier to use and smooth."
anti-Apple(fan): "Your sense of reality has been warped by Steve Jobs. Here I've written down the list of features not found on iPhone. See how many you're missing? Numbers don't lie. If you still buy the iPhone, you're irrational.
A potential iPhone buyer: "I still want to buy it. Man the mobile Safari is amazing and everything feels amazingly smooth and nicely sorted."
anti-Apple(fan): "Arg! I can't believe Steve Jobs has made another fan with his Reality Distortion Field! See here I'm copying and pasting on my Windows Mobile phone! An iPhone can't do it. Here I have my external memory card which gives so much more extra room for cheap, with the iPhone you're throwing away your money to Jobs. I know you're usually a rational guy, how can you buy the iPhone?"
A potential iPhone buyer: "But Windows Mobile phone feels clunky and hard to use. The iPhone feels much more intuitive."
anti-Apple(fan): "Jobs is deceiving you. He wants to dumb down everything and make your intelligence level go down. You want a phone with nothing but a big red button? That's intuitive! If you're a rational guy, you'll have no problem using Windows Mobile. Also look here, I'm using my finger nail to move things around with a GREAT accuracy. The iPhone can't do it. See how many features the iPhone is missing?"
A potential iPhone buyer: "But Windows Mobile just doesn't feel right. And the iPhone feels so much better made than Windows Mobile phones."
anti-Apple(fan): "Trust me. You've been brainwashed by Apple's marketing. The iPhone is a fad for people of lower intelligence. Who cares what the outer shell feels like on a phone. If you're smart and rational, you want and need more features. Windows Mobile is better. The iPhone is an expensive toy and will fail."
