Religious preferences aside, I'm pretty confident in saying that if a tablet needs to be in the mix, the iOS ecosystem is going to offer more solutions then Android or Windows 8 right now.
Heh. Did you look at the contents of those lists? Aside from Intuit GoPayment (didn't know about this one... good info), none of the apps listed provide any of the requested features. Instead, you get "Dictionary.com", Facebook, CNN, and MBA-ish apps.
iOS may offer "more", but I'm not convinced it offers "more solutions". ServiceBridge and
ServiceMax (different company from ServiceBridge) are cross-platform, and
PacketTrap appears to be cross platform -- all of which appear to meet the requested requirements.
