I am thinking of giving up my stresfull job in corporation and do something creative But to start with I would like to first spend a couple evenings porting some of my old ideas to ipad and try to sell it to get some courage that I can live on it and it is worth to spend few $k for Mac, various iPad,iPod,iPhone. Can I sign up for developer program and use my jailbroken iPhone for testing without resorting to loose the jalbreak and all cydia stuff? What about Mac - does it really matter wheter it is Core 2 duo with 2G RAM or i5 with 4G or more RAM? I have no experience with Mac Right now I rather consider buying old Core 2 duo with Show Leopard. Are there out of the box application for graphic development on OSX? Graphic developement is the only thing I can think of which will run better with more RAM and newer graphic card. I have already learnt objective-C and have hughe knowledge/experience so I am confident of giving a try but you know there are costs of living and I do not want to add now hughe costs of HW/SW before I start earning. Thanks in advance! Edit: Well, I just noticed that the c2d mini has DVD drive whilst i5 mini doesn't have. That's tricky decision.
