Please note: this is NOT a tutorial on how to make your computer flatter, only faster.

Buy a 90GB+ SSD

- Buy a 2.5" external hard drive enclosure if that laptop is your only computer.

Replace the hdd in your laptop with the new SSD.

- Throw the hdd into the 2.5" external hard drive enclosure.

Transfer your current install from the hdd to the SSD

and Voilla, you converted your laptop to an ultrabook-like machine!
