Is it really an iPad? Or a laptop? Most of the geeks I read on-line say that the iPad is pretty useless.
Those "geeks" think a device is "useless" based on a spec sheet; they reach that conclusion without trying to use it or considering how people in the real world use computers.
If you can do it from a (Flash-free) Web browser or e-mail client, you can do it from an iPad. For that matter, there are remote access clients that let you remotely control a Mac or Windows PC from the iPad. I doubt the president is doing a lot of photoshop or video editing.
