Question

I have been reading a lot about ios 7 on my ipad 2. It suggests I should wait before updating,  is this wise advise?

Answer 1

iOS 7 will be and undoubtedly already has been extensively tested, but there can be errors that are missed during testing.    Errors either in iOS itself, or in specific applications you're using.
If one of those errors is key to your environment or to an app that you depend on, then you can be at a standstill until the problem is resolved.
Which leads to the usual recommendations: either have a scratch device and test the update there, or at least wait a week or so — a week or so for a heavily used product such as iOS and for common applications, longer for less-common operating systems and applications — and see what gets reported by others.
Do we know what those errors might or will be, what part of iOS might be effected (if any), or what specific features of applications that you depend on might be perturbed?   No.
Some of us will be somewhat slow about updating to newer OS X Server releases — unless we need a specific fix or update — just so that the more common issues can be sorted out by other folks, or where we use and run the updates on test systems where we can afford that; on hardware configurations that we can update and see what (if anything) fails with the update.
In terms of an iOS update, the most you'll probably effect with a failed update is yourself.  Worst case, the phone is bricked, and one user (you) is out.  With OS X Server, you can adversely effect dozens of folks with a failed OS X Server update or with a bricked server box.
If you still want the New Shiny (and who doesn't?), then definitely have a couple of recent backups of your data.  Before you update.
