No, this is really NOT a travel technology question... however, I know there are some great tech minds on here so thought I might as well draw from it.

My iPad plus my smartphone does all I need on the road. (I don't travel for work) but at home I need a real computer. I enjoy using premier elements to do youtube videos and a type a lot of emails plus blogging. I am sitting on 2 laptops, one 14 inch which has served me well for almost a full year and recently purchased a 17 inch to be able to have more screen room for editing my movies and photos. However, I am going crazy with this new 17". I hate the touchpad on this new computer and the keys are not much to my liking either, I kept thinking I would get used to it but I haven't. I decided I wanted a desktop with a real keyboard plus a bigger screen than the 17". So, I went to Best Buy yesterday to look for a desktop and fell in love with the all-in-one's. I never knew they existed!! The huge 23" touch screens, they are just like having a huge iPad but with a keyboard....

I was a good girl and forced myself to walk out without buying one to do a little research first, so..... I am wondering what their downsides are compared to a traditional desktop?
