If Apple brings forth the cloud solution, I think this can have a major effect on pc computing. iPad in the current state is a great extension to our main computer (notebook, desktop). Once, it is activated. It is fairly independent from the main computer except for updates. It serves most purposes for a majority of the population: email, games, browsing, reading. There is a learning curve to adapt to tapping versus typing. However, bluetooth keyboard is available. If apple brings the OTA (over the air) activation, OTA software updates and OTA backups, then the need for a main computer becomes less important. Again, I am talking about general population for home use or school. It will be interesting to see how powerful iPad 3 will be. Would a quad core iPad serve better for heavy duty work like final cut pro or complicated computational diagrams, etc? Storage is an issue. The cloud solution may work or thunderbolt to a portable storage. iPad 3 with a thunderbolt would be awesome. Will iPad ever help apple in "halo" effect to boost mac sales and kill netbook sales? I am seeing the halo effect for idevices and mac computers. It is starting to have an effect on netbooks. With the cloud solution and thunderbolt in the future, it can kill netbooks for sure.
