I have not used the pico scope, but another designed and manufactured in holland.
Before I purchased the unit I looked at quite a number of "PC Scope" spec sheets.
The biggest disadvantage these scopes have compared to more traditional Digital 
scopes are their trigger circuits. The trigger circuits of a typical modern digital scope 
are orders of magnitudes more advanced than the circuits on the PC Scopes. It seems
that most of them capture the data via the A/D circuit and then do a software "trigger"
on the data. This is not fast or consistant enough to trigger on glitches etc.
