thankyou for the upgrade, I’m currently recommending a fuze to two other people to buy (and upgrade to 16GB). However as yet another Rio Karma owner I’m going to wait for Gapless before jumping. For now I am planning to mod my Karma’s with Sandisc 32Gb CF cards.
However it is really nice to see innovation back in MP3 players and if you can recreate the capabilites of Karma’s you’ll see a lot of people who care about music heading your way.
I really look forward to the day when I can help pay your wages 
thankyou again
