If MS Word is one of your top go to applications on your laptop, then you’ll do well with Pages - an iPad word processor. You’ll be able to work with screen keyboard or a wireless keyboard. While you’ll get some useful features, like endnotes, footnotes and embedded graphs, you won’t have the full functionality of Word. Unless you’re writing a book or making heavy use revision tools with collaborators this app could be enough. Available from Apple, Inc. for $9.99.
