I have the same predisposition towards SPB software. Kirvin does say Shell is very good, and in general the commentary seems very positive.. but I see SPB software as bright and shiny (after trying Pocket Plus *shudder*), geared towards looking good in screenshots & on your device while not really adding that much in usability and definately packing on the bloat.
But I'm willing to be proved wrong!! Apologies in advance
