GSMArena needs to start reviewing windows 8 (non-rt) tablets is they want to cover the current market of tablets. It's outdated to draw the line based on proceccor (ARM) or OS.
I, for one, have a Samsung XE700T1C tablet with a Core i5 processor, 4gb of memory, 256gb ssd, etc. I can assure you, if you have one of these, you'll never look back at Android/ARM tablets.
