On the Dell Streak, when you login to the default Facebook widget, you assign the Dell Streak app to your Facebook profile. Conveniently, Facebook automatically tracks the amount of users using an app, so we can kinda track how many Dell Streak users there are in circulation (well, at least those who have signed in using the stock 1.6 Facebook app at some point).
On the app page
, you can see this figure now is at 21,000 monthly users
Prior to the US launch, this figure was actually around 12,000 so we've seen a bit of growth but from the US launch but the Streak was out for 2 months before in Europe.
I think with better marketing (well at least some
marketing over here in the UK) this should have been a lot better!
