Has anyone copied a few hundred MB + onto the PB and then launched or used an App?

I'm finding that during file transfers the Launching of applications is quite slower.

As well does anyone care to comment on the speeds of transfers themselves?

I'm finding it at about 3-5MB/sec which seems fair enough, I'm wondering if anyone knows how quicly the iPad 2 can transfer at.

Moving 64GB of data @ 5MB/sec would be horrid taking somewhere around 3.5 hours.

My 16GB PB is already close to full and I'm finding it to be very responsive. I'm quite impressed with it. It's nearly as fast as my MacBook Air 11 and much much better than either iPad, neither of which really impressed me. We gave the iPad's to the kids loaded with games and videos. I'm finding the playbook (despite it's name) to be a much more serious device.

Edit: Not sure about actual MB/s but it's pretty quick. I'll try to do a test later on with all three devices and post back.

I was watching an episode of Spartacus while I was xfering a 1.36 Gb file to my PB, no slowdown.
