"But so far, Flash has been one of the weakest, most embarrassing spots for the Galaxy Tab, severely depleting the device's performance, according to the reviews we've read. (We don't have a Galaxy Tab, so we weren't able to verify this ourselves.)"
From Gizmodo's review:
"The browser is miserable, at least when Flash is enabled."
From the New York Times' review:
"Because the Galaxy runs Android 2.2, it can also play Flash videos online (touché, iPad!). Or at least its supposed to. After some delay, I got Flash movie trailers and CNet videos to play, but at ESPN.com, the Play Video button just stared at me sullenly. (My Samsung rep says they play fine for him.)"
From the Wall Street Journal's review:
"I tested several Adobe Flash videos and websites written in Flash. Sometimes they played and sometimes they didnt. In all cases, they slowed the browser down. On one site written in Flash, I got a warning saying I might want to 'abort' lest the computer become 'unresponsive.' In another case, the Tab crashed. So I conclude that while the Tab does play Flash, it needs work on that score."
From Engadget's review:
"The Tab's Flash capability is a nice fallback, but if you've been thinking it's the killer tablet app you should think again."
