One reason for Spb Pocket Plus is to add what WM left out. Especially for the PIE. Also os-VGA and SE-VGA, BatteryPack Pro, Mem-maid and many others. If I upgrade to WM5 will I still need these or similar products?

If so then the upgrade - even at $50, might be worth the investment. Having to purchase add-on software adds up in expense.

So those who know, what can we do without in the WM5 - and what will we still need?
