Need help comparing Laptop specs

I have a Mac desktop from early 2008. Has a 2.4GHZ Intel Core 2 Duo, 4GB 800MHZ DDR2 SDRAM and 250GB of storage. It's starting to run pretty slowly, so I was browsing Mac laptops just for an initial comparison.
The MacBook Air has a 1.4GHZ processor, 4GB of memory, and a max of 256GB storage.
How the heck is this an upgrade from a computer I bought 7 years ago? I get I'm moving from a desktop to laptop, but 2.4 to 1.4 processor? What am I missing here?

Clock speed doesn't tell the whole story. Completely useless to compare frequency across architectures. Every new generation of CPU is more efficient than the last. More transistors in less space, more IPC (instructions per cycle), and lower TDP. The low power mobile i5 in the macbook air is probably twice as fast as that old desktop core 2 duo.

Also the Macbook air has DDR3 Ram, which is faster than DDR2, and the SSD is much faster than a spinning hard disk.
