It looks like the new Macbook Air will feature a new, faster SSD. It will also likely have the Thunderbolt connector.
As for Lion, it has many changes to the interface compared to Leopard and Snow Leopard. The latter had many changes under the hood but visually was the same as Leopard. It introduced more 64-bit code, shrunk the size of the install by quite a bit and improved performance. I upgraded to Snow Leopard as soon as it came out (I got it for the price of postage).
Lion will have a lot more gesture based features like the iPad. So either a laptop (with multi-gesture touchpad), the Magic Touchpad or Magic Mouse will be needed for this. Also there is:
- Mission Control which replaces Spaces and Expose (both very useful)
- Launchpad (iPad like way of launching applications)
- Fullscreen apps
- Resume - resume an application and continue where you left it
- Versions for files (keeps old versions automatically)
- Airdrop (share files with those nearby wirelessly - no wifi needed apparently)
- Improved Mail client
Will I upgrade - almost definitely yes but might way until others have proved there are no major bugs.
It has not been confirmed but some are saying you need to be on Snow Leopard to upgrade, i.e. not Leopard or Tiger.
They have also dropped Rosetta so PowerPC binaries can no longer be run. I wonder if this is more to do with IBM buying Transitive which underpinned Rosetta rather than Apple pulling the cross-processor compatibility solution?
- Lion Server - no longer is there a separate OS for servers... it is now an addon to the workstation product.
