with regards to baby operating classic so called 'prone to major tech problems' aircraft, I know for a fact that when the shiny new bmi airbuses which are indeed being leased by baby in the light of the late arrival of new leases have with almost immediate effect of flying the busy baby schedule flown straight into tech problems which weren't there when they flew the bmi routes one even had an engine shutdown and divert enroute!...its not nessesarily the aircraft its a tough beating for any aircraft to take and thats the nature of the flying which goes for all low cost airlines including the previously mentioned ryanair, easyjet and Flybe. The only difference being that Baby don't (unless they HAVE to) cancel flights and ditch the passengers, they get the aircraft fixed or swapped and still get the pax where they want to go. These tech problems are a product of the business not the aircraft and they are common throughout.
