Is iMovie for the iPad worth getting?

Hi! Okay so I'm getting an iPad 2 in about 2 weeks and I want to know if the app iMovie is worth getting? I have a YouTube account and I make videos so what I would do is make the video on my camera, send the movie to my email and then open it on my ipa and save it so I can edit it on iMovie. So is iMovie worth buying? I have a PC so I can't get iMovie and all I have is windows movie maker. Thanks
