Apple is not Palm, it will be around for a long time. As for Palm, I had $9,000 in Palm stock almost wiped out in a short period of time. Not completely, it became worth $1 to $2 total. Funny thing is lots of people were buying Palm devices as the company went under. Apple is a stable company, and the stock price will eventually go up again.
The next big thing, will be the resizable tablet....imagine a device that could be the size of an iPad Mini, but could easily expand to the size of a regular iPad or even larger, if you want to watch videos on it.
