Is that a PC in your pocket?
TheRegister has an interesting article that covers some of the comparisons of available software between the Nokia N80 and the N70.link
From the article:
The Nokia N80 is typical; it runs Symbian 9 with Series 60 version 3, and offers enough improvements over the N70 to encourage people to upgrade, but when they do they are finding that even quite expensive applications aren’t being supported.
The hugely popular TomTom MOBILE GPS system connects to a Series 60 handset which then displays a map and directions, but not on a Series 60 version 3 handset! According to TomTom, it’s up to the customer to check their website for compatibility, and they won’t say when, or if, they’re going to support version 3 of Series 60.
Last time I bought a PC I don’t remember checking with the producers of all my software to see if it would still work, but when you’re buying a new phone you might want to do just that.
A quick check of SymbianGear reveals that the N70 (Series 60 version 2) has over 300 commercial applications available for it, while the N80 has only 75. In freeware, where resources for porting and signing are more restricted, the situation is worse with only 10 programs for the N80 while the N70 has over 210!
That’s a frustration that Symbian is offering incompatibilities again, and it is definitely one of the main reason why the OS has not really grabbed a larger audience.
