you are really showing your ignorance here...
1) iPod/iPhone accessories a more than a 1 billion a year business (this is not including Apps).. i'm sure someone could make money at it.. and if they are selling you the software i'm sure the price of the mount would be included..
2) i lost my PowerTap CPU last summer and it was $220 to replace.. basically the same price as an iPod Touch.. i guess $220 is a cheapo unit in your world... well i guess the iPod touch is equally a cheapo device for you too, so what's the difference?
3) i guess your powerTap CPU has, maps, routes, directions, elevation, % grade, optimized on the fly pacing stategy, TSS etc, etc.. not to mention the potential for coaches to track their riders during training and racing etc... i guess you got the deluxe model??? LOL!
HELLO!! it's in a protective case.. and yeah it seems like it's every other day that i find myself riding in a hail storm... not to mention it's wireless.. so you could just put it in your damn pocket for Christ sake.. i don't know about you but i don't find myself even looking at my powerTap CPU when i'm being pelted with painful hail stones so i don't think i'd be missing anything by putting it in my pocket..
