Recently I have begun flirting with my shiny new Blackberry which is gradually taking over from my Treo 680 as my main device, why? Palm is great, nothing will replace the simplicity and ease of use of PalmOS however Garnet hasn't moved on at all since it was released back in 2002 and it is starting to feel it's age. That combined with pressure from work has made me move over to the shiny new Blackberry 8310 'Curve'.
Since 'moving' i must admit I miss my Treo for a lot of things, the lack of a touchscreen I have got used to as I rarely ever used anything but the 5 way nav on my 680, but I miss the abundance of software that make Palm OS one of the best mobile platforms around, because of this I haven't stopped using my Treo entirely but it does get left at home most days. Software for Blackberry OS is far more commercial oriented (the target market can afford it) and as such there is very little decent freeware and shareware for BOS which I miss, although now I have a battery that lasts me 5 times longer than my Treo which is the best plus point so far.
As soon as a fresh device based on ALP or Palm's own OS is released I will be ready to jump back on the boat and return Palm to it's number one spot as my smart phone of choice, until then I have succumb to RIM, albeit begrudgingly (with my Treo as a mistress on the side).
