Searching for a used MacBook with CS5 MS already installed (they are out there, but I semi question the legitimacy of some as they have no media included, just preinstalled), and I am starting to also question on whether finding one with CS5 is really important if my main purpose is to learn Xcode, write iPad apps, and teach my oldest girl how to do the same. For those of you with CS5, how useful is it for App creation? What other applications should I be looking at with those goals? I have found I can get a decent 2.4ghz dual core with 4GB ram plus HD for around $400 (without CS5). Thanks!
