New tv.. help

Hi, guys.  I hadnt read that much about tv's before I purchased my new toshiba regza 37'' lcd hdtv for 1000 bucks.  The picture quality has been really good so far though I dont have any hd channels and ive only been seeing 360 games in 720p and 1080i which look pretty sweet.  However, my tv dosent support 1080p.  Should I think about returning this tv and going for one with 1080p or go ahead and keep it ? In the store it looked amazing showing 1080i programming and that is what sold it to me.  It has a lot of inputs ( 3 hdmi, pc inputs, tons of others).  So do you guys think I should just stick with it even though it dosent support 1080p ? The reason I went for it is because of the 1000$ price tag really.New tv.. help
