Owning an iPad 1 and an iPad 3 ("new iPad") I'm always thrilled to see how they perform side by side. It's like night and day - unreadable, low-contrast vs. superb, super-high-resolution display; 5 seconds for opening Mail vs 0.5 seconds; almost tripled battery life (at least for me). For some aspects, it's an improvement of an order of magnitude within only 2 years. I don't think such an improvement will be possible in the next 2 years, and the only incremental improvements in the iPhone 5 seem to support that. You can't really upgrade a tablet (yet - there is at least USB host support in most Android tablets), but consumers won't be as hard-pressed to buy an iPad 4 and 5 as they were with earlier versions. There is already the highest-sense-making display resolution, apps open almost instantly, and superlong battery life. What more can you ask for given its restricted use case of media consumption? It will again all be about software (Siri for iPad, tighter TV integration, perhaps OSX on iPad?) soon.
