Yes, Asha(S40) is not included because only Nokia sees Asha as smartphones while the analysts don't.
As the asha lines is the successor to many of the earlier s60 phones you get pretty meaningless stats if you exclude the asha phones.
Either you should exclude many of the earlier s60 phones or include asha.
While it's debatable whether Ashas are smartphones or not, calling S40 a successor to S60 is a bit of a stretch. UI-wise maybe, but certainly not in functionality.
Besides, sales of "Asha full touch smartphones" fell almost by half QoQ (down 46% from 9.3mln to 5.0mln) while total handset sales only fell 28%. So they are becoming less relevant inside Nokia even. The most likely cause is competition from sub-$100 Android phones.
I have yet to see a non-laggy Android phone, including quad/penta cores. I haven't used 4.1 or newer, though.
The point was more about the hw anyway - if a brand name can push that kind of hw at that price, having a tiny-screen Asha with antique hw is not going to cut it.
Versions of Samsung's Galaxy handsets that use their own in-house Exynos SoCs come in very close to near non-laggy as opposed to those that use SoCs from other suppliers. Why Samsung has to use different SoCs for the same phone in different parts of the world remains a mystery. Remember the Galaxy S2? The versions powered by Samsung's Exynos processors were said to be more fluid than those that made use of Nvidia's Tegra SoC.
And for some people, animation lag is a huge no-no. And my (only) experience with an old Asha phone during a Nokia roadshow some years back was that they generally appear rather fluid for their antiquated hardware.
There's now a $99 Android phone from a big name manufacturer, with an IPS screen and a quad core cpu. (Archos, introduced today)
Bit hard for Asha to compete with that.
I'm sure Asha only is a temporary solution in the wake for cheap windows 8 phones. I suppose the scrapping of s60 and meego indicate Nokia don't plan to develop a smartphone os long term on their own anymore. The Asha development is probably easier to streamline with the regular s40 development. If I remember correct they have now windows 8 phones around 200 Euro (maybe cheaper in some countries?) so the space for Asha is shrinking.
Actually the $99 Archos phone (35 Carbon) is only single core and not that exciting over other $99 Android phones like the Huawei Y201 Pro.
WP8 devices are now down to $180 (Lumia 520) but they don't compete with Asha at all because the latter sell for $100 or less. WP8 still has a long way to go until it reaches $100, not only because of minimum hardware requirements but also because vendors are locked into a very limited number of mobile SoCs.
The problem of lagginess is much overstated I think. In that market segment, it is most important whether or not people can afford a smartphone at all. They will happily accept some jerky animations in exchange for browsing the Internet, installing apps, etc.
