Really in my opinion I think the other two parts of the 3in1 are useless anyway. The web browser sucks and rumble doesn't really add anything IMO.
Yeah I thought that the rumble would be sucky too but it's really grown on me, I like it. The web browser is meh but it's handy if your in the middle of town and you have
to send an email. That is if you can find a free hotspot. (They're usually around EB Games.) The GBA support is just awesome and runs some programs better than the old SupercardSD for sure.
I'm waiting for an update as well because I recommended the 3 in 1 to a friend and we got one of the new ones. Took a bit of explaining but I convinced him to wait. Hope it comes soon.
