Im looking at buying a MacBook over the summer and have been looking at two different models, the Air and Pro models above, does anyone know roughly how much faster (or slower) the Pro will be compared to the Air. My immediate reaction would be to think the Pro would be loads faster due to the much higher spec but having had a go with them the Air certainly seems to benefit from the SSD - any comments appreciated! Thanks =)

The 2.3GHz dual-core Intel Core i5 in the MacBook Pro (MBP) is significantly faster than the 1.4GHz Core 2 Duo in the MacBook Air (MBA), but the Flash Storage in the MBA (note it's not quite a SSD) is faster that the hard drive in the MBP.
To decide what to get, you must understand where the speed increase will come from. The Flash storage in the MBA will speed up your "experience" in a bursty way - things will load faster. The speed increase from the CPU in the MBP is more "sustained" - tasks such as video encoding will be faster.
Also you have to take into account the MBA has no optical drive, Firewire or Thunderbolt. Ethernet is present, but it requires a USB NIC. However the MBP is heavier, bulkier but with a better battery.
So if speed is the deciding factor for you, get the MBP and possibly spend the extra on a SSD for it, then you will have the ultimate 13" configuration (if you really want speed then get the 15" MBP with an i7). However for most people, buying the MBA is more of a lifestyle choice - it's lighter and more trendy and most people don't do that much encoding/compiling anyway.
If you let us know exactly what you want it for, I could be a bit more specific.
