I do like the concept of wireless routing/networking capabilities and integrated design of using Time Capsule w my new iMac 1tb HD (STILL not here yet), but am wondering if my 240gb WD HD is sufficient backup storage for the time being. Maybe I can just spend the $300 for 500GB Time Capsule later on? Or should I just spend the $$$ and stop my sniveling? Once my iMac is delivered, should I take it to the Apple store and have them set it up, or is the setup easy enough for a Windows refugee to handle? Please give me your feedback regarding this matter. Understand that I really have no wireless networking experience. Anyone whose read my previous threads will further understand that I'm currently a Mac Noob (virgin), and any elementary additional help is greatly appreciated. Thanks in advance.
