How to sharpen Fuji X jpegs?

If I get myself a XE1, I want my pictures to look sharp when viewed on my ipad3, as the pictures of my EM5 have a sharp look and I dont want to loose that

Since most of the Fuji owners use jpeg (because of the obvious lack of adequate raw support):

What procedure/tools would you recommend to downsize and sharpen X-E1 jpeg files to look great and sharp on an ipad3?
