Really not bothered. It just needs ssh to get to a server and I'm good. Why run commandline software on a phone when you've got multiple 12-16 core servers with 64GB RAM and an SSD RAID array to hand?

No, that's a launcher.

Unless the apps have their own custom UIs then they too are using the UI framework that the OS provides and it's this that IMHO looks and feels a bit dated on Android and iOS. That's the problem with being spoilt by the N9's lovely UI.

All OSs provide UI frameworks (eg Sailfish's Silica) and design guides and generally developers follow them so the apps look and feel like the OS dictates.

You do realise that people on the other platforms will think Sailfish and Maemo's multitasking where you have to manage tasks yourself and they don't close when you leave the app and don't save state is even more painful to them. As a Mac user it's a running battle with Windows users in the office explaining why if you close the last window in a Mac app so there's no visible windows open, it might still be running in the dock.

IMHO there's a middle ground. N9's UI with Android style state saves and Sailfish 1.0's covers and pulley menus. Plus keep full old-style persistent apps running if the user allows them.
