1080i is higher definition BUT as it is interlaced, the moving picture or dynamic resolution is worse than 720p.

1080p would be ideal but would take twice the bandwidth of both 720p and 1080i. 720p and 1080i have almost exactly the same bandwidth but as 1080 is the bigger number, most broadcasters use it.
AFAIK all VM HD and SKY HD transmisions are 1080i. BluRay is 1080p.
