I didn't notice wobbly diagonal lines on iPads until I got an iPad mini 6. Not a big deal since the mini is too small for me to draw on. My previous iPad Pro 10.5 with ESR tempered glass screen protector had didn’t have wobbly lines even with the screen protector on. I recently tried the 11-inch M4 and it has a slight wobble on its diagonal lines, and with a tempered glass screen protector, it definitely makes wobbly lines.
I’m returning the M4 iPad Pro and still keep using my 10.5 inch iPad. I can’t justify the upgrade when the new tablet is a downgrade in line quality.
Yeah that makes sense, I was thinking of getting new iPad Air but it has 60hz refresh rate and I already got M2 iPad Pro's lying here somewhere, I was hopping to sell them both and get new one but my dream setup is iPad Pro 14" or 16" with Mac OS capability where I can use it as a laptop outside with keyboard and draw at home like Cintiq while connecting it to 27" display. Right now the way I use it doesn't justify the price tag. I can pretty much do everything I do with it with regular iPad as well.
Samsung s9 has great price in where I live (istanbul) m4 Starts from $2000 here where a s9 ultra 14,6" with 512gb 12gbram + pencil is $800.
what I hate about samsung is their customer service here. Otherwise all app that I use (photoshop, infinite painter, sketchbook, nomad, shap3d) are available on android as well.
New Surface pro is also very promising on paper so far..
