RIM is in much better shape carrier wise, balance sheet wise and customer wise. RIM was at CES many said they weren't, they just didn't release BB10 there.. they did speak about it. That may be driving investors from CES as well.
Even with Palm those in before launch sold for $4, a 33 percent premium to the $3 pre launch price. At this point, this is a somewhat educated gamble. Greed will do you no good. Don't panic on the daily moves, and at the same time do not rejoice either as tomorrow it can all change on the sentiments of the market.
My advice ( nobody hosting, or will ever pay for it) is to treat this like the gamble it is today. Set your limits and play within it. If you hit your target price, sell and be happy. Ensure you set your loss limit as well.
My best to all on what is sure to be a rollercoaster ride over the next few weeks.
