I've used every version of Windows since Win 3.1. and currently use Vista. And Windows Mobile (even though it's not a desktop OS) is the most horrendous, user-unfriendly, bloated and buggy mess that MS dumped on its users. I bought an HP ipaq after debating hard between iphone and ipaq. I simply didn't want AT&T contract and wanted to be able to open office documents among other things. I chose the ipaq. It amazes me that version 6 (the one on my ipaq) is that bad. How can it be version 6!??? is beyond me. After months of trying hard to get used to using it and depending on it, now it sits there in my draw abandoned. $299 gone and it's one terrible feeling of sadness and anger.
