I recently swapped my Asus B101 for a Nokia Lumia 2520.
The i5 processor on the B101 was amazing but it was 4 year old technology and the battery lasted a wee bit over 2 hours. It was killing me when I had to be mobile with it.
The 2520 has a sweet Snapdrgon 800 quad core at 2.2ghz. Plenty fast enough for me.
Do I miss the x86 abilities? Not that much. I never really understood why Windows RT was so poorly received. I guess people could not wrap their minds on using a tablet with Windows. Have you ever used an x86 app with a touch screen??? It's murder. Really. I have my desktop at home for those applications. I really don't need them when I am out and about. And, when I did use x86 apps on my B101 it was nearly always with at least a mouse. Now you have to drag a mouse around with you.
Yes, there could be more apps in the Microsoft store but seriously, how many apps do you really need?
1 billion? Really?
There is barely anything I could do on my Android tablet that I can't do on my Windows tablet AND I have full Office on my tablet, access to a nicer interface, Onedrve interfaces better than Dropbox or Drive on an Android.
I would pick a Windows RT tablet anyday of the week over and Android tablet. And would prefer it to my full laptop for mobility a lot of the time.
