I need input soon please? OK, I like if possible that some one (or any) could give input in this to category's? 1-1750 mAh vs original OM battery, how much time will extend it? (e.g. same applications) 2-the original (even with the up killer) won't last me 8 hrs. Please don't guess your answers! or put any thing that you have not experiences or some one said? I truly need input, or will the extended 3500 mAh will be a better choice?
