Bare with me on what may be dumb questions. I switched to MAC 6 months ago and love it! I still have my PC desktops but my PB laptop totally kicks azz. I've never been able to figure out the following: 1. In Windows I can click on any item and hit my delete key to send to trash. Can this be done on Mac? 2. When I download files from the internet or view a PDF online it always saves them to my desktop?? 3. In Windows defrag keeps the hard drive performanc tuned up. Is this needed on a MAC? 4. In Windows I can view my folder files as thumbnails. Can this be enabled in MAC? 5. Right click & save to saves any file to directory you specify in Windows. What is the easiest way to do this in MAC? Thanks all!
