It's very easy to use for beginners but also has advanced features that allow users with more experience in editing videos using other software packages such as Adobe Premiere Pro or Final Cut Express/ProtoCinema Xpress (FCPX).
The program can be slow at times when working large libraries of footage so it could definitely benefit from faster hardware if you're going this route! I'm currently looking into alternatives due to an upcoming move out location which will make importing files impossible without additional hard drives etc., however there are some great online services like Amazon Cloud Drive where one simply uploads their media library directly through cloud storage rather than physically transferring them onto your computer before uploading - saving time & hassle while still keeping all original data intact within Google Doc format meaning no loss should anything happen during transfer process.
