Hey guys, I currently have a June 2008 iMac 24" Screen 3.06GHz C2D 4GB DDR2 RAM 1TB Hard Drive 512MB 8800GS Wireless Keyboard Magic Mouse Snow Leopard The problem being it's too big for me. I've moved house 3 times in two years and I'm moving house again come June (I'm a Uni student). I also want to be able to take it with me, to my department and to my GFs house which is a bike ride away, so pretty much carrying it around most days. My concern is that the MBP will be a massive step down for me in terms of responsiveness and speed; I don't play games and I don't do any 3d work, though I will be doing some openGL programming next year, nothing major but it will be need to be able to keep up. I also want to play back HD video. Will the integrated intel graphics be able to handle this do you reckon? And for those who have the 13" now, how does it compare in terms of having many applications open, will it be really slow compared to my iMac? Does the screen real estate get on your nerves or is it something you can get used to and does the text size seem smaller than the 24" (this is a biggie). I know the new MBPs aren't released yet, but I wont be expecting anything more than a speed bump or maybe an i3/i5 in the 13" with intel graphics. Sorry for the long post, thanks.
