I was kinda looking at the dell Axis x30
hxxp://www1.euro.dell.com/content/products/productdetails.aspx/axim_x30_wireless?c=uk&cs=ukdhs1&l=en&s=dhs

but i've also seen the new Asus MyPal A730

The asus has not been released yet and will probably cost alot more that the dell. It will be used mostly for business and possibly sat nav at a later date !
Any other recommendations are welcome !

I've been looking at handtops recently, the oqo looks pretty sweet but its not released yet. If budget isn't a concern, have a look at it:

Thats just slighly out of my price range I was wanting to pay around £300 ($540), but if I had that kind of money the oqo looked sweet !

my dad has one of these:

I can tell you its a sweet, sweet little machine

If I was you I'd look at the things you need it to be able to do and then look for something covering those. Also, decide what OS you want (WinCE or Palm)
