Fitbit or something else or wait?

Limebird

So I've been thinking about getting a fitbit force, what's the prevailng opinion out here?

My problems are 1) extreme inability to find time to work out at all. 2) I like to do the eliptical machine but worry it wouldn't track it well. 3) I like the sleep monitor aspect since I have trouble there with two you g kids waking me up a lot.

I know there is there basis b1 but it's too expensive to justify on a whim.

Does a good fitness device need to track heart rate. ?

Is the factoring in of weight / him done in the apps?/software?

Wait for the next generation maybe ?

As you can see several unknowns these days.
