Thinking about acquiring a computer

I have been thinking that even I will eventually own a computer of sorts --after I retire and have the $$$. So, I have been thinking about what kind of set up I might like to have. Certainly nothing that takes up a lot of space. I was having a
discussion with my tech-savvy friend recently about this very topic. I was thinking of buying a lap-top w/ a wireless card-- for portability. She suggested that I look at Zonbu. Wow, this was exciting because of the small size and all the good stuff that comes loaded on it for a small price. So I spent some time on the Internet looking up articles on this and what I saw was impressive. I have more research to do, since there are critiques re: slow speed, etc. Also, it appears that it would not be practical if I want something portable, though I have heard that there are folding keyboards and portable monitors ......so now I will have to look for info on these.
