1-If there's nothing else than creating and managing documents, it won't matter.
2-You'll have to use picasa for photo editing
.
3- Security is fine( it's google).
Go for it!
Very best
Did you just say security is fine because it is google? Google is just as insecure as Windows. Android has tons of holes alone.
OP, for the basics it is fine. However, it wont support all the software you might be used to and will feel a little weak for some things, such as photo editing, compared to Windows based programs.
As for security, this is a cloud based system so it is secure to a point, depends on how secure Googles cloud servers are and these days, servers from even big companies are being proven hackable.
Honestly I would only get one for basic tasks like web browsing and maybe document editing but I can tell you that Google Docs is nowhere near as powerful as Microsoft Office and Picasa is not even near the same level as Photoshop or GIMP. Just based on my uses.
