cyberfox,
I dont think a new lynx would be worth it. The new Atari portable should be based on the Jag system. and i guess if you have enough money to do so, I would get a hold of Ben at http://www.classicgaming.com/vcsp/
he has done a few portables, the 2600 first, then he did a protable PS and a portable SNES. I am not sure why he hasent tried to do a portable Jag. he seems to have the access to machines to make his own cases for these units too. I bet if you give him a Jag, some $$ and your desire, he would be interested in making a portable Jag.
Honestly, a revised lynx would be nice and all but then you would need to have new software for it, and who is gonna do that? a portable Jag already has a great line up of games.
doing a portable Jag does have some issues though, do you make it use the CD's too? his portable PS used the CD's but thats all the unit needs to run, here there are carts as well as CDs. I think one would have to make a choice on which software medum to support. unless there is a way to get the software off the carts and onto CDs, or vise versa.
anyhow, thats my imput, I do own a lynx and i think its a pretty good unit. sure it could have been better, but time and tech, are the only things to allow that growth. and if the company cant keep up, then others will fill the void, example: nintendo gameboy.
