Hello guys, I'm new to digital photography. Just picked up a Sony DSC-H1. Am using Picasa 2 for now. Seems to fit most of my needs. But later will be ordering a MacBook Pro laptop. What I'm wondering is, as my digital photography experience grows, if it will still be worth purchasing PE4 knowing I have iPhoto '06. Would it be justifiable? Or can iPhoto do pretty much everything PE4 can along with being well intergrated with the other iLife apps? Also, have any of you PE4 users run into any problems? Bugs? Or has it performed near flawless? Thanks in advance!
