Yea I've got an iPad 2 and the thing I love about it which the iPad 1 doesn't have is the forward facing camera as I use that all the time to Skype my overseas family.
Other than you can see the speed test comparisons on Youtube with a 1 and a 2 side by side and the 2 is definitely quicker than what people make out. The real difference is when you're running a few app via multi-tasking then iPad 2 with its dual core processor takes over.
