The webOS keyboard on the HP TouchPad generally works well.
Copy and paste in webOS works almost identically to the way it does in iOS.
Our reactions to the TouchPad's calendar app were more mixed. It supports multiple calendars and displays each in a different, pleasing pastel shade, and the buttons at the top make it easy to turn each calendar on and off. However, when you flick between days it has a strange habit of defaulting to one o'clock in the morning, meaning you have to scroll down to find the time of day when you're awake (and so are likely to have entries in your calendar). It's also the slowest-running of the TouchPad's integrated apps we found it fairly jerky when scrolling around.
An Office-compatible editing suite has yet to appear in the HP App Catalog. This is a serious drawback and one we hope will be rectified soon.
Although you can open Word, PowerPoint and Excel files sent to you as attachments and the TouchPad lets you view documents stored in the cloud at Google Docs, looking is all you can do; the supplied Quickoffice app doesn't have an edit function and an Office-compatible editing suite has yet to appear in the HP App Catalog. This is a serious drawback and one we hope will be rectified soon.
Office files on the TouchPad look but don't edit.
