now christmas is over we're thinking about getting a new 'puter and the macs have been recommended I have lots of questions though and probably more as I know the answers to these is a laptop or a desktop model better? Can I use the same programs I use on my pc? is there a minimum model I should look at? how different is it for example how easy will it be to find my way back here on a mac? anything I should try and buy with it thats needed to make it work?
