I did the reservation. I decided not to upgrade my Tab S9 Ultra to the Tab S10 Ultra.
I was afraid of the mediatek processor. Reports were good, and the screen is antireflective which I think would be nice to have. I have the antiredlective display on my S25 Ultra, and it is great. I tried the Samsung antireflective screen protector, but I could not stand it. It had a couple of dust spots and another bubble that just drove me crazy.
If I can continue to use my Book Cover Keyboard on the Tab S11 Ultra, I think it might be a good time to trade. The trade in value on my Tab S9 Ultra isn't going to go up. I might as well get the newer screen tech and reset my years of updates.
If the Book Cover Keyboard won't work on the Tab S11 Ultra, I am out. At $350, I can't afford to buy a new one with every upgrade. And it seems that Samsung no longer likes to give discounts on that case with new tablets.
