[Teclast X98 Air 3G] vgiozo:
Received my x98 Air II + Win8.1 (HG6N) on Wednesday, having ordered on the 11th, that's pretty fast shipping if you ask me. New record for parcels.

PROS

- The tablet feels very small with the thin frame, much smaller than my Onda v975m or maybe I grew out of habbit having sold it a month ago.

- It does look like it is of a little higher construction quality, with my Onda I did get a few creaks while playing with the tablet, not with Teclast.

- The screen is very beautiful and bright, no shades or dead pixels.

- The speakers are of higher volume than I expected

- Thankfully I have no issues with the camera orientation or the screen refresh rate.

- First opened it had 86% battery installed. From Wednesday afternoon till Friday morning I downloaded and installed over 1.5GB of updates, played with the device quite a bit, tested various apps, played with settings etc. On the whole seems quite good in managing power.

- Charging is faster than expected. Went from 7% to over 80% within 2-3 hours, then almost the same getting up to 99% (on first charge it didn't make it to 100%, dont know why)

- Internet browsing is a joy with this tablet, so fluid, its really great.

CONS

- The cables that come with the tablet (USB data + OTG) are really low quality, some of the harder, more unflexible cables I have ever dealt with.

- Touch screen responsiveness is indeed mediocre. Not a deal breaker but certainly noticeable.

- I don't know if it is an issue with graphics drivers but when there are popup windows, like when installing a program, resolution and rendering of fonts seems to suffer, almost looks grainy; you have to move them around a bit to get a better focus on them

- Camera is poorer than other chinese tablets.

- Speaker sound although of adequate volume is more "hollow", of lower quality than my Onda v975m.

- Windows environment is certainly laggier than Android and Win8.1 is neither here nor there...if you have it on a desktop it's a pain in the ass with the Metro apps and screen; if you're on a mobile device you still need to go through much of the desktop UI, which is quite hard, small buttons etc.

Also the gestures even you get used to them, it's just not as "natural" and easy as dealing with Android.

- Windows store kinda sucks compared to Google PlayStore

- Subjective thing: My main reason for getting a tablet is reading PDF files and annotating them, without having the background fan noise from pc/laptop and just having it right to my (paper) notebook, transferring it much easier around.

PDF editing/annotating tools in Windows for touch devices suck major c*** though...nothing compared to PDF MAX I use on adroid. Usage of PDF MAX is seamsless, choosing text, choosing annotation type and style, adding/deleting annotation, all done with a couple of touches, no effort.

Can't say the same with about Windows PDF reading/annotating apps. Best I've tried are Drawboard PDF, Foxit PDF reader. First of all rendering is really slow and tiring, you need extra clicks to choose what annotation you want to add, and then choosing the same annotated text again to delete the annotation or change it is really difficult they just don't pick it up easy nor do they have the same easy editing process.

That to me is a deal breaker...I can't have a tablet which I can't use as I want to read and annotate pdf files; not if it costs 150+ euros at least.

Found "Xodo Docs" that does the trick!

QUESTIONS

1) Do you know of any good PDF annotation Metro App?

2) Microsoft Office 365 is preinstalled and as I have read, if I use it, I get to have my OneDrive space upgraded to 1TB!!

- Is that space only available for free for the 1st year along with Office, or is OneDrive permanently upgraded to that storage space?

- If I uninstall Office after upgrading my storage space, is that upgrade annulled?

Thank you.
