I went this route with my Asus Transformer TF-101 (ie first generation Transformer) about a year ago and it's been an overall good experience. Like Renegade, I was pleased by the improved responsiveness and smoothness of the tablet. Having said that, it's a good thing that I'm "geeky" because I had to do a lot of tinkering to solve a range of issues (early FW releases of ICS from Asus reduced video output volume to almost nil and there were early random restart issues that have subsequently been only partially resolved by newer FW, etc.) in the first few months. It's fairly stable now, but Honeycomb was rock solid. ICS is not... Note, though, that vendor ROMs vary wildly in terms of stability, depending on vendor, the hardware components, yada yada yada..
