I am the proud owner of a December 2006 Macbook Core2Duo 2GHz with 2GB 667MHz DDR2 SDRAM. I am going to buy a new Mac soon, since I have the opportunity to present this my laptop to my sister. I am using the computer at least 10 hours every day, 4 hours making music with Logic, 2 hours playing Football Manager, 2 hours with Internet and 2 hours for watching films, listening music and so on... What I need is something really powerful in terms of calculation and ram (for Logic and Football Manager) and with a decent graphic card (comparable to a ATI 6870). I was thinking about getting an iMac when it will update, but I am often relocating (once in a year, by plane) so I think that maybe for me it would be better to get a Macbook Pro with 17". Would I lose a lot in terms of performance\price ratio? Is it a good idea to buy next week (if it will be out) a new Macbook Pro 17" with Snow Leopard when this summer will be available new iMac and Lion? Thank you in advance for your kind suggestions!
