I need two advices for my laptop (Powerbook G4, 1.65Ghz) and my MacMini (MC238LL/A C2Duo 2.26Ghz). Powerbook Need a battery for it but i need a recommendation on what to buy: new i think i need to find it cheaper than 100$ or used or used i have no idea where to get a reliable cheap used battery and should i? MacMini Need to connect it to my LCDtv but i have come across 3 solutions and i dont know which one to choose. So question is which one and why? 1. http://www.monoprice.com/products/p...=10428&cs_id=1042802&p_id=5969&seq=1&format=2 2. http://www.tekserve.com/store/1503/Mini_DisplayPort/-4989 3. http://www.tekserve.com/store/1503/Mini_DisplayPort/-9471 On the 3rd option, im not 100% sure but i think main diff is that i supports 1 channel audio only whereas 1&2 support two channels. Am i correct? and if so, what about the comparison between the other two (1 & 2)? What are their differences, they do have quite a price difference... right?
