I used to be indecisive, but now I'm not so sure.
How is anyone supposed to help you with your choice when you offer no further information as to what you intend to do with either machine.
The E1705 is a totally unsuitable machine for running OS X or iPhoto, iDVD, Garageband or iMovie. However, it does have the ability to run thousands of virus programs that will not run on the Mac. The E1705 will run Windows, but I'm not sure you could put that in the plus column.
The iMac is very suitable machine for running OS X or iPhoto, iDVD, Garageband or iMovie. It also has a much larger screen with a higher resolution. It can also run Windows but, once again, I'm not sure you could put that in the plus column.
Were you asking a specific question or just trolling around?
I cant decide wether to purchase the Dell E1705 laptop or Apple iMac.
