I'm the cheap sort, didn't even consider the flyer until the $200 price drop. That said its become my favorite small tablet. Along the same theme, I didn't but the pen for $80 at Best Buy when I bought the tablet but waited for two days for the black $30 Ebay bought pen to arrive. It looks like the real thing except in black not silver and doesn't come with the AAAA (that's 4xA) battery. Considering that it saved me $50 I can deal with the limitations. For the thirty I paid I'd say the stylus is worth it even if its just for notes and the occasional annotation via picture which is all the pen can do now.
I had tried a number of write with your finger apps and they all left me cold. Not a one produced anything like what I was able to do years ago with a stylus on a resistive screen. I much prefer the advantages of the current multi-touch capacitive screen over those old resistive ones but bring able to mimic minute movements on screen is not their forte. The difference between my finger and the stylus is night and day. Just being able to joy down a sketch that's readable and usable is wonderful. I've stopped looking back on resistive screens with fond nostalgia. Supposedly it will do much more under honeycomb. For now, for its limited use, I'd say its well worth the $30 I spent but not worth the $80 list price.
