Have spent a lot of the festive break reading these discussions and still can't decide between 11'' or 13.'' I will be replacing a G4 PB which is acting as my desk top. My main needs are: email, internet, Office, music storage and photography( playing rather than serious user!). I suspect the 11'' may do for my needs, but the 13'' seems 'better value for money' and perhaps more future proof? I could sum it up by saying: my heart says 11'' but my head says 13!'' I need to buy before Jan 4th to beat the UK VAT rise. If I spend any more time researching this on the net, either I'll go mad or my wife will leave (tempting choices! -just kidding!) Any help gratefully received.
