@nilchak, danramos: What you're both talking about is something that I've been thinking about for a while. I've been using various Sharp Zauruses since the SL-5500 and I've been using Nokia Interrnet Tablets since the N800 was released. There's definitely been a ton of hardware improvements in that time, and there are certainly some things that the Zaurus hardware just isn't capable of doing at a usable speed that doesn't even make the N8x0 hardware sweat (such as web browsing). That being said I think a lot of people would still be using their Zauruses if the Zaurus community hadn't become so fragmented that development ground to a halt. Part of this fragmentation I blame on Sharp for their poor communication with the community (and their eventually abandoning the software they made leaving users and devs no way to move forwards). But that just set the stage: It was the lack of a communication and agreement (and sometimes the presence of ego) in the Zaurus community that really led to so many different, mutually incompatible, device dependent distros. I think for a new dev not only having to deal with cross compiling is a big enough hurdle, without having to figure out how to cross compile 3 different ways and target different versions of different distros, some of which only run on one device.
I think getting to the point where a new developer can target phones, internet tablets, MIDs, and tablet PCs with just one source tree/source package is where we need to be to make developing for Maemo/Mer attractive enough to be sustainable.
Sorry for rambling, but I get so frustrated when I think about all the wasted effort and the early irrelevance of the Zaurus hardware that could have been avoided. I really hope we can work together to avoid that same situation here.
