Hello guys.. Off late i have been trying to buy one of the iMac or A730 from lenovo. I am a stock market trader who needs a really fast system and aesthatically pleasing because i would be looking at monitor for almost 12 hours a day. The lenovo A730 with the touch screen actually blew my mind until i noticed that it runs a hard disk at 5400 rpm, which would substantially slow the performance of my system. I am an user of macbook from 2008 to 2011 and later moved on to windows system because my work mostly involves running programs that werent available for Mac OS X. Would you suggest me to go for iMac and buy a program like parallels or Fusion to run the windows applications or do some tweaking to the A730 and get along with the windows system ? Personally i prefer using the iMac, but i have got some doubts if parallels will run windows programs with the same speed and efficiency they run on windows systems? Is parallels trustworthy ? I dont really want to use bootcamp, because if i am running a windows OS for 12 hours a day, i would better buy a windows system. So, Can i really trust parallels to run the programs without any lag or crashing ? Is it A730 or iMac ? Do help me.
