The main fuzz about ipad2 is it's thinner and it has facetime now. But the new Samsung Galaxy Tab is thinner and a little lighter than ipad2 and most of people don't know it.
About the facetime, ipad has a front VGA camera and a 1MP back camera. Samsung has 2 MP front camera and 3 MP back camera supporting 720p video recording.
Ipad 2 don't support flash but galaxy tab does.
The new Nvidia Tegra 2 dual core processor is 2x better than the ipad's processor and this supports gaming much better.
The samsung's display is obviously better than Ipad's display. The Android 3.0 supports better multitasking than ios.
So if you;re looking for something like ipad but not ipad, galaxy tab is the best option. If you're looking to compare ipad or galaxy tab, it's really a preference. If you like ios, go for ipad. If you like android, go with galaxy tab. But the main disadvantage with galaxy tab is, it has less apps for now.. But then again, it's just for now.
Ohh and btw, I own a 3G Samsung Galaxy Tab 10.1...
Happy, have you tried the new galaxy tab? It's kinda bullshit that you say ipad 2 is "obviously" better.
