Eventually, she will throw the iPad out of the window in frustration if she uses it for email. It might be OK with a dedicated keyboard, but I’ve not tried one so I can’t honestly say.
The iPad is great for some web browsing (but not anything with Flash in it) and other media (we have lots of bob the builder and fireman sam on ours to keep little entertained on long drives), but for email use, it’s only really a read and file tool, not a response tool.
Weird, email is fine on the ipad.
As for flash, if i happend to find a site that uses soley\mainly flash then i would just close the browser on my PC and move on, too long to load and generally horrible navigation.
