Hi !!! I recently bought an ibook, (not yet delivered). I will be using an audio recording software called Audacity to do voice recording and I will also be using two software programs for architecture - Archicad and Vectorworks. Will i need to update the RAM to 1.5 GB, (by buying an extra 1 GB), or should i be ok with 512 MB. Who do you recommend me to buy from? Is, in your opinion, Data memory systems the best source to buy quality products, with good prices, are they honest. Who else would you recomend, if not them? If i were to order from Data memory systems, which memory should i get (out of the four that they propose for the 12" ibook). http://www.datamem.com/parts_that_fit.asp_Q_submit1_E_1_A_MF_E_APPLE Thank you, igmolinav.
