Funny...i don't have that button problem...any who the jornada 568 is a great unit. Although it doesnt have the amount of accesories that the compaq has it does have a built in cf1 slot and a sexy keyboard. i would sugjest the 567 over the 568 because it is cheaper. the only differnce between the two units are the software the is included. the 568 has two more programs then the 567 but one of them is absolutly pointless. you can see them at the programs are:
CodeWallet Pro (semi usefull for storing passwords)
And
AccessPanel (stupid idea, i hate it)
thats the run down.
