Hello everyone, i am new here and have 2 questions, First off i am looking into buying a Mac to replace my POS Dell. I am looking at buying a refurbished Mac, is this a good idea, i take good care of things i buy and just curious if any one has had or heard of problems with buy refurbished Macs? Second question is, i go to college and constantly on the move! So i am looking at getting either a new MacBook 2.4 or a MacAir. I don't game and don't run many programs, besides office program and the internet, also i do not download many things, but i do know i want to buy and learn how to use adobe photoshop. So i am just looking for some friendly advice. If you have to ask me any questions to better give me an opinion feel free to ask! Thank you!
