I am begging the ol' parents for a refurbed mac from the store online. Being the "shylock" my dad is, i sent him the list with all the refurbed airs. He will choose the 1,299 one. Which are as follows: 1.6ghz 64 gb SSD <-- better than the 1.6 128hdd right? (Space is not a problem for me i have about 20gbs of music/movies and thats it) PLease no comments telling me to get a macbook or macbook pro. I've done my homework but still have a few questions. Is the one i chose a rev a, b, or c? Will i be happy with its performance? Im basically using this for word, itunes, web browsing, maybe a little photoshop here, and msn. THats pretty much it. Do i really need to get a 1.8ghz or even get this runcore thing everybody on these forums is talking about? As long as after 4 motnhs of being used, it is still able to open safari or itunes in under 5 seconds, im pleased. Under the usage im using does anyone expect me to encounter any probelms? Video wise, etc.. How does the battery stack up? Like truthfully, if using it do write 1 word doc, browse 1 web, bluetooth off, airport on, 80% brightness, and itunes music running how long am i gonna get out of it? Ive been hearing stuff like 2 hours 15 minutes and im getting worried. After buying the mac, (if i get one) do i really honnestly need to upgrade to this runcore? Any other info on this would be much apprectiated And by the way, i am comming to mac from pc for the first time. I am currently using a 1.6 ghz Intel Atom n270 w7 eee pc 1000h 10.1'.
