got an x3 this week. love that i can keep it in my little shirt pocket, etc. reading more already vs scrolling. buttons for the win, really. the bezel left right and top are, imho, perfect.
The x3 is actually slightly newer too, but I was already wary of the 4" size so I went for the x4. It ended up being just fine though.
yeah. my x3 seems to fit fine in my notebook holder next to my 3x5 craft paper notebooks. or shirt pocket. i might change to x4 once they start shipping again but i have already read a bunch on the 3 … its size may work out fine. i daily carry an iphone 15 the small one… and i think thats similar in size to the x4?
The x4 is smaller than any semi-recent smartphone I am familiar with, but maybe. The x4 is smaller than a 3x5 card, so this has me doubting that the x3 is truly smaller.
