My Powerbook shipped with Xcode 1.1 which I have installed. Should I bother updating to 1.2 or 1.5? Or, should I plan on updating when I upgrade to tiger (which I am assuming will ship with a newer version of Xcode)? I am only learning to program with cocoa / Xcode with no previous experiecne (wierd hobby huh?). I am not doing any serious work and hope to learn enough to try out some simple projects. Is upgrading a necesity, or will 1.1 work well for me? Can I continue projects started in 1.1 in a later version of Xcode if I don't update to a newer version now? Thanks for any advice!
