As another user of the device, I would respectfully disagree with some of your points.
Right now Efika MX Smartbook is kind of dated both in hardware and software, but it came out in 2009 and almost all of the products that came out 3 years ago would suffer from the same issues. The internet is significantly "heaver" those days than it was before and HD video is now common while it wasn't so much in 2009.
I am using various devices like several tablets and notebooks and yeah, Efika is the weakest one mostly. Still I do use it.
It was proven to be particularly useful for:
1. Checking e-mail.
2. Browsing internet. It is mostly possible to access web pages, there are only few exceptions that are heavily loaded with stuff.
3. Writing all kinds of stuff. I mostly use plain text editors, but I also used LibreOffice.
4. Opening pdfs - it works great.
5. Watching pre-encoded videos. Sometimes I watch lectures and stuff like that while I'm traveling.
I find it's really usable and if you love keyboards, like I do, it's definitely a better alternative than most of today's tablets when you consider the price. I also think it's perfect for students who don't need more for their tasks.
- !!! It's glanced !!! Who thought that a glanced surface is good for a portable device? You will never see it clean.
- It's impossible to use any IDE on this device. It all will be painfully slow. It's ok for vim / emacs users, but still may be critical for someone.
Well, Efika is not a professional developer device unless you want to program for ARM for some reason. I personally didn't try any IDEs for it, but it's clear that it will have some limitations as a developer machine.
- You can browse only pure HTML web. There a lots of reasons for that, firstly because the only available browser is firefox, which can be slow even on mainstream PC's. Much faster Chromium doesn't work on this device, at least I haven't seen it working on Debian armhf system (it works fine on unofficial Debian armel). And forget about HTML5 and other AJAX-y stuff.
I disagree about "pure HTML", but, of course, everyone has different standards. For me it's just ok.
- It's impossible to use this device for watching movies. Forget about "Multi-format High-Definition hardware video decoder". Officially it works only on Totem, but even then you will not want to see this video. It's more like a slideshow.
I made a small script for encoding videos to watch them on Efika. It basically changes resolution of a video to 360p and encodes it to h264. No problems at all even with 60fps and it looks nice full screen.
Re-encoding is not a problem for me, because I have a fast desktop machine.
- It's possible to use this device for watching youtube. You will even get the picture. But you will not want to see it either.
- Device needs to be recharged every night, even If you don't use it at all. Even if you haven't touched the device, next day battery will be empty.
- Max FPS that I could can get on this device with glxgears is around 22 FPS.
- Sound quality is appalling.
This all is true, except that sound quality is actually better than I expected. I mean, I've seen a lot.
Anyway, personally I purchased Efika just out of curiosity, thinking it won't be of use actually. But, I actually found that I like it and I do use it. Of course it doesn't compare with devices like the new iPad, high end Android tablets or ultrabooks, but those devices come with a price tag and personally for 199$ I would prefer a device with a keyboard than a cheap tablet without it.
