Lenovo Yoga 3 (2 GB RAM)

I don't think so. You cannot work directly. I mean you may have to download Excel and Word viewer for android from the internet. I think Word file opens in it by default but editing will not be possible unless you have the suitable app for this. If you want to work out with MSOffice files, then you can buy another version of the same machine which runs on Microsoft Windows OS instead of Android. That piece of machine will for sure support all the MSOffice applications.

Yes, you can work.

Definitely.

YES.

I don't think there is any tab which can support the external HDD access. How are you thinking of connecting it with the HDD first of all? It doesn't have any USB connection. You can try connecting using Bluetooth or Wi-Fi which I have never tried till now. Yes, I connect/ accepts the 128 GB MicroSD card successfully. I hope it quenched your query...cheers.

No, it only supports a 128GB memory card.

Yes, it supports via OTG cables.

No.

Yes

Yes, you can upgrade it, but for the time being it is giving you the most advanced version and after some time when the new version comes you can upgrade it for a couple of times I believe. Then the newer version may not support this hardware and then you have to satisfy with the same upgraded version. So, a couple of upgrades is what we can expect.

Yes, you can upgrade. But it should be officially announced by Lenovo.

Yes, it can be upgraded to marshmallow.

NOT YET.

Yes.

Yes, It does support WhatsApp, provided you have a valid SIM card with you. Because when you connect it for first time, it will ask the OTP that comes on the registered mobile number. You may have to download the WhatsApp app personally from internet.

YES, IT SUPPORTS.

Yes.

Yes.

No Idea. I think that only the manufacturer can tell this. Right now you have 16 GB HDD and 2 GB RAM in the Yoga 3 version. It is a good combination. It has removed the front camera, which I did not like. Overall it is a good piece of machine.

Lenovo yogatab 2 Pro is the upgraded version of this

No, only the 2GB version is available.

Yes, tab 3 pro.

As of now, no.
