That's like saying don't buy a iPad 2, as a iPad 3 is round the corner. There's always going to be something better.
I got my Transformer overclocked to 1.4 and running quite smoothly even with a live wallpaper.
It's not really like saying that though, I think there are clear faults with this generation of Android tablets and I'm a massive fan of Android phones. I don't actually believe they should be classed as fit for retail.
Tegra2 has issues, all these are detailed in the major review sites and there shouldn't be a need to overclock a device to run parts of the shipped OS, of which Live Wallpapers are.
Google need to manage their hardware partners better, there's still a clear gap in performance in regards to gaming performance and battery life versus the iPad2
The Application Market is now in a good position as too is Google services and applications, their efforts should be concentrated on the above in my opinion.
Again, a massive fan of Android and I was impressed by the Honeycomb UI versus it's mobile phone OS siblings but whilst I have money burning a hole in my pocket at the moment, I certainly won't justify spending it on buggy hardware/software.
