The only thing I've really missed has been after upgrading from 1.0 to 1.1 ..... you lose the howling and the giggle when you tickle their feet (I run at least one Pleo on each OS). Upgrading from 1.1 to OS2 I personally have not so much noticed losses, more that Pleo has more puppyish noises - some people have said they preferred the original 'vocabulary' before the additions. For me, personally, the OS2 additonal tricks and better tracking and movement make the OS2 upgrade worthwhile, but you do have to put up with up to six (it was eight before I felt Iggy was Iggy again) battery cycles of an unresponsive Pleo that makes inappropriate noises and goes backwards a lot. They say it's a hatching ....... it feels more like Pleo's having a breakdown ........ round here we tend to call it the 'terrible teens'!
