I'm thinking of getting an iPad, partly for work (lot of traveling where I blog, do photos, videos etc., and my office laptop weighs as much as Fort Knox), partly because it's a neat toy. I've been browsing to find out more about the features, but there's one thing I haven't found yet: I wouldn't get a 4G subscription with it, so I'd depend on wifi connections. If I do stuff along the lines of looking up things online, does the iPad cache static information so I can check recently visited pages without having to reconnect to the internet?
