I bought an iPad 2 this year and may very well also replace my five-year old iMac with the latest version (or possibly a MacBook Pro). But I'm wondering how Apple's new iCloud service will impact my computer purchases going forward. To wit: Up to now, I would always buy a computer with the fastest and most-powerful processor, the most RAM and the biggest hard drive I could afford in order to handle the heavy-lifting involved in post-production and rendering of still images and video, and the storage of both. But will cloud services mean I can go with the entry-level equipment, like a base iMac or even a MacBook Air, allowing me to spend more on photo equipment? Will all the heavy lifting will be done by cloud servers? I get the impression the cloud is offering not just storage but actual work. I'm a Mac user but this question seems applicable to PC/Windows users as well. Has anyone else been wondering about this? Do we have any conclusive answers or are we really in "we'll have to see" mode?
