You are out of your fricking mind -- buy the wifi SD card and the keyboard or -- buy a netbook and get a CPU, hard drive, screen, battery, etc thrown in for free.
I will entertain your reply for just a short moment.
1. Nothing is "thrown in for free" There are always cost associations. Some food for thought, that also goes for software. - A comment such as that will make your credibility for intelligent conversation go down the drain.
2. You are missing the real point of my comment above.
