iWroteReview Comment:
- You can't add more SSD or RAM later
- $999 is the best price but  beware that you'll have real hard disk space left for use only around 49GB
- If you want to use it other than surfing the internet, email, office task. Please upgrade to 4GB Ram
- If you want to use boot-camp feature.  Please consider 128GB model or higher
