I don't demo my Playbook because I don't need to justify it. The people who were truly interested have asked me if they can use it, and that was enough to show them what it's capable of.
they both run perfect on mine. i always show my friends a full 1080p video on youtube. it shows how smooth it runs and the beautiful quality of the screen.
hmm, I dont know. Im 10ft from my router, getting +20MB internet. By the time the music starts, it is slowing a bit. The wall of thumbnails moves nowhere near as smooth as the RIM commercial nor as smooth as my PC. That was also with a empty cache and local content cleared. Nothing else running except this Crackberry tab.
Id love to see a decent quality recording of someone showing that page running as flawless as RIM shows it as.
Edit: Just ran a speedtest. 28MB down. Basically matches my wired speeds.
