I am a a designer for over a year and my main working base is powerful combo of two 27" iMacs. Next step I'm planning is to get something more portable for remote work and that's where my dilemma starts. I am thinking of MacBook Pro with retina or iPad 4. I know iPad is just a tablet but with today's apps development and adobe great photoshop touch, ideas and few more creative apps you could really start design on iPad and finish off with finish touches on iMac. I also like touch based factor which speeds things up. Unless there are some things I am not aware of. What is your experience guys?
