Yes. You found the difference.
About the e405... Even with a heavy discount to under 200 bucks (here) I only see one feature that could sway me to look at this over the Axim X30. That would be the Voice Command, but having used voice command products, I know it's not something I'd call a deal maker.
The top of the line X30 has Wifi, which at that price is attractive...
I noticed that HP has both a H1940 and a H1945 model. Does anyone know the difference between these two? I can't see much of one other than 1) CNET doesn't have nearly as much info on the H1940 as the H1945 and 2) On HP's website, one is listed under Home & Home Office and one is listed under Small Business.
In general, I'm looking for a dependable, entry level Pocket PC (switching from an old Palm m105). I'm also looking at the Toshiba e405. Any opinions? Other ones I should be looking at in that general price range?
