hmmm.. just tested yesterday and today,

i'm currently online in the default conversations with 3 accounts, 5 microbs open, facebook, tweego, cutube-qml (not running any videos currently) and it's showing a little bit of choppiness...

when first connecting to the 3 accounts, it did show hildon-home almost crashing but it recovered... so didn't have to reboot... not AS smoothsailing as the very first patch
