Still deciding wether its worth it to cancel my digi edge for this. Its not so clear cut

Pros:
- When below the cap, 3g speed is faster than edge.
- When below the cap, 3g is cheaper monthly for lowest package

Cons:
- When passed cap, 3g is throttled, actually slower than edge
- When passed cap, monthly rate could be double of edge
- 3g coverage is limited (but will eventually grow)
- 3g cannot use on mobile phone

seems like a a pretty sour deal for compared to EDGE.

Am I missing something?
