So, not a lot of news for the 405 device then.
In fact, none at all !!
So, do i buy one, or a 605 ??
Answers on a postcard to . . . . . . . . .
i have both, the 405 is an ok unit but not an upgrade imho from the 404. the 605 is out of this world in comparison, better battery life, MUCH MUCH better res screen, more toys (ie web browser, touch screen, widgets, games), + more support. but these things come at a price. the 405 is more stable than the 605, i only had a few recovery mode screens come up on the 405 but its more constant on the 605 (but workable) but hopefully this will eventually become a non issue with new firmwares. I found the battery life close to terrible, well no where near the quoted amount on the 405, the 605 is a lot longer lasting (my 605 is also flash).
the 405 is on the other hand a lovely size, it fits in the palm of your hand. there is only a few squids difference in price between the two units (605 flash) you will be pleased if you invested in the better machine if you decide to go that way, there is also a LOT more support for the 605.
