21 vs 27 iMac...which one do l really need?

I'm really starting to consider if l really need the 27' screen and could use some "words of wisdom" from those that have had an iMac before.

Some Notes to consider: I'm a new iMac user (switching from PC)

*I'm not a computer gamer
*l do some photo editing, not much if any video editing
*Outside of some online games the kids play, no real video/movie watching
*Will be used for School, kids art stuff etc...
*l have not intention of reselling the machine...l'm a "keep it till it's done" type person

Although the 27 monitor is beautiful, do l need one that is that big. l think the 21.5 would suffice (l would pimp out the 21 inch if l had to).....Any and all advice is greatly appreciated.

Thanks Again Everyone.

Much appreciate the response, cheers

I'd go for the 27 inch if you can afford it. It's the one thing you'll never be able to upgrade in your all-in-one. Plus, it's amazing.

Thanks for the response, my dilemma is not the cash it's just that I'm afraid the 27 inch may be too big for my kids....
