i have late 2008 MBP with this specs : 15.4 inch screen 2.53 GHz C2D 4 GB RAM 2 nividia cards my MBP is working fine and i like it. reasons for getting imac : larger screen and better resolution which i think watching videos will be better then my MBP (although i don't have any complains when watching on my MBP) it looks cool, lol more powerful then my MBP (2.8 GHz i5) so i can play some windows games, although i don't like about 80% of widows games like strategy,FPS and role-playing games. i already have ps3 for gaming but i like to play some games in 60 fps where you can only play them in 30 fps on the ps3. the problem with this is that you have to replace the gpu about every 2 years but i don't know about these stuffs. how is the speakers ? better then MBP's ? better when watching movies and gaming ? one last thing : the internet connection sometimes disconnect from my MBP because my room is far away from the router, the chances this happens is 5%. i will not buy the current imacs, i will wait for the next update. so what is your opinions ?
