As the title says, I am looking at buying a 21.5" iMac soon. This will be my first ever Mac (first Apple product actually). My daily use involves the web, email, light MS Office work, light photo and video editing, and ripping of CDs/DVDs/Blu-Rays. I hope to keep this Mac for a good while (5 yrs min) before upgrading. For example, I am still on an old Dell laptop that I bought back in 2007. After reading the posts here, I have an idea in my mind what I would like to purchase. I would prefer to hear others' opinions based on my use to see if I am on the right track. FYI, I do not see a need, nor have the space, for a 27".
