Hello again everyone. I am planning on buying either an iMac21"(3.60GHz i5+ 8gb ram) + iPad [OR] an iMac 27" 2.93GHz i7 + 8gb ram. I really cant decide, and really need your advice. I will be using it mainly for photoshop/autoCAD/inDesign/illustrator/Games etc. I wonder if this iMac27" is actually a lot faster and more powerful than the iMac 21" mentioned above?(well, can normal people tell the difference? eg when using photoshop or playing game etc?) I cant really decide because I do want a powerful machine to use it for a few years, but yet 27" may be a bit too big and heavy as i 'may' have to move to another country- and i hear that 21" is quite ok in portability..(well its not THAT bad compared to 27"..?) (but I love its hardware, so powerful) what do u all think? plus, if i get an 21" imac, i can afford to get an iPad for 'laptop' use..(tho can someone advise me whether iPad is actually that useful? To me its just a bigger version of iphone? and i do own an iphone 4.) Your advice will be much appreciated and i wish you all the best - have a great day wherever you are.
