Here is the head to head shoot out between old and new…

Using an SSD hard drive really makes things a lot quicker.

The Boot time and load time is significantly quicker,

Apps just load up in no time.  You seriously become inpatient when using any other computer with a standard HDD.

Also, the portability of this things is just awesome, its so light that you can hardly notice it in your bag, its just like carrying around a book.

Do I miss the DVD drive? – no, i have the external USB drive and I haven't even used it once.

only thing i can fault is that it has a max of 4GB RAM. Its definitely acceptable, but 8GB would have been sweet though.
