So, three generic aluminium-clad Androids made by Foxconn, and one more cute basic phone on the rather awful Series 30+ platform [1]. I wasn't expecting anything else, really, but still feeling a bit disappointed...

The Series 30+ operating system on these devices is kind of weird. It's basically a generic clone of the old familiar Nokia Series 30/40 phone UI, but made by MediaTek instead of Nokia itself. I guess what happened is that the internal featurephone OS teams were terminated when Microsoft acquired the business, and they just picked up the closest replacement from the Chinese clone masters at MediaTek.
Now, the atrocity that was the OS for the Nokia Asha phones, that is a completely different story.
I just wanted a small dual-sim phone, don't need any other features than the ones it provides.
I know J2ME was not really good, but they managed to get something even worse. It's almost* impossible to develop applications to their new phones.
* http://mre.mediatek.com/ is down for good since the start of 2017 and they announced that they would shutdown in 2015/12/31, so I don't think there's any official way to download the SDK.
Seems like it will ship with an integrated Opera Mini btw, as one of the press shots had that stylized O as one of the icons on screen.
The problem is that Opera mini is a MITM browser that does not handle neither real HTML nor WML. This makes it so that not only most web do not work, even web apps with old WML interfaces will also not work.
So, some tasks, such as checking your e-mail or IM, are almost impossible. Note that if J2ME was supported, you would at least be able to install an e-mail/IM client (even if it was a shitty one).
As for "IM", phones already have that. Its called SMS.
