Hi Having gotten entirely fed up with the sluggish performance of my pathetically underpowered Windows based laptop (an HP Presario with 2G ram) I'm thinking of making the move to a Macbook. As well as the usual stuff (Firefox, MS Office, Skype etc) I'd like it specifically to be able to run some basic video editing tools (iMovie/Adobe Premiere) and Flight Sim X. Two things that I would dearly love to have some feedback on if anyone here has any first-hand knowledge... 1/ How does Flight Sim X run on a MacBook (is it even available??). Not overly fussed about it being on the top setting but would like it to be able to run at least a little more smoothly!! 2/ Can't afford to buy brand new. Reconditioned is fine. Realistically what should I look to pay for a second hand Macbook.... and what's the minimum spec that holds up these days - especially with the idea of video editing/gameplay in mind. Any thoughts / suggestions welcomed Thanks in advance.
