I find the Birdy to be lighter and faster than a Brompton. The Birdy has a more road bike like cockpit, and I can adjust it to mimic the measurements I use on my full-size bikes. While not as fast as a real road bike, the Birdy can still fly quickly.
Besides the 10 speed driveline, I installed XTR brakes and levers, and some titanium hardware. The cheesy stock rims are wearing out, so I will upgrade the wheels shortly. I am also considering getting a better crank set, the stock chain ring works well enough with the 10 speed chain, but the chain guards are too wide, and occasionally the chain slips off the ring and gets stuck between the guard and the ring.
All in all, I can't think of a better folder than the Birdy, my other bikes are getting dusty.
I'm also looking at improving various components on my Birdy (although, it doesn't really need it). I really haven't had a chance to fully detail the bike yet and closely inspect the rear cassette. I know the chain needs to be replaced, and the hub needs a little tuning, but everything else seems OK so far.

Regarding your chain issue, are you positive that you have the correct length chain on there? You may need to remove a few links if your chain is slipping.
