Hello! I'm a new switcher, and I'm on my 3rd day using my mac. Love it so far! Not much defects at the moment. Only maybe a bit too hot while playing wow. Goes up to 70c sometimes. But I think it's ok.... Anyways I have a few questions. Would appreciate if you answer it. 1. There are some trial softwares such as Aperture, iWork, Microsoft Office... I won't be using them, and they are hogging the hard drive space. Is it ok if I delete them? 2. Since I'm new to Mac, if I "delete" them in windows, I have to UNINSTALL it...how do I do it in my mac? Do I just drag the file to the trash can, and empty the trash? 3. I would like to ask how should I treat my battery. Right now, it's at 100% charged. Should I remove it? My friend told me that if I leave the battery 100% charged, and I'm still plugged to receive power, the battery will deteriorate faster....is that true? 4. Can my mac view High Definition movies? (I have a 15.4inch version SR MBP) Also, in Leopard, it says the DVD player will receive an upgrade...so does that mean I can start buying HD DVDs or something? Or do I still need to upgrade the 8X Superdrive? Thank you for your time. Really appreciate it!
