I eventually wound up doing that, but I still prefer the DS Lite's holder location.
One other really stupid design flaw: The analog stick. I mean, ok, it's a nifty, responsive device, but you really should have stolen Sony's concept here and had it be a textured analog stick. My thumb never slipped on the PSP's analog stick, but the 3DS's stick is very slippery, which gets really annoying while on timed things (like the race against Ingo at Lon Lon Ranch).
