The Tab is a Samsung device, unless a lot has change since I last went looking. Both mine are.

Yeah, it is samsug. shit I said Spny didnt Il At any rate went back looked at the same size S. Yup the 4 works better for me that the S in spite of the much higher S pixel count. So I guess I can just repeat eyes are weird.

The Tab S has the AMOLED Display and one of the features of that is individual pixel control. So when the black parts of the screen have the pixels turned off instead of dimmed. And also it has somehting like richer color. It's the same display that's on the Galaxy S5 and the Note 4 phone. But the ipad Air 2 has an anti glare screen the Samsung tablets don't. Although I wouldn't be surprised if they started adding those in.

We just got in the new 27" iMac with 5K Retina display and it's very very pretty. Someone claimed they couldn't see the difference but I think it's the default Yosemite wallpaper, once we put on different pictures you could really see it.

I have one of the 5K Retina iMacs and the display is amazing. It makes the 27" QHD resolution monitor next to it look so grainy, and that's just crazy.

I know - the tab 4 does not come close to what the S has - not in display, not in most other factors. But something in how my eyes don't work right make text on the S look fuzzier to me. The particular flaws in the 4 work well with my eyes. I don't understand it, but I was in Best Buy comparing the two side by side. I do not pretend to understand it.

Interesting thought. The Galaxy tab 10.5 is slightly bigger than the Galaxy 4 tab 10.1 4 whole tenths of an inch.) I did note that the Galaxy tab 8 was suprisingly close for me to read to the 10.1. And the 30 and 40 inche screens seem to do nothing for me. Just out of curiousity I'm going to look at the Galaxy Tab S 8 inch - see if that slightly smaller screen works better for me than the 10.5 inch. My brother said if I can find something that works with my eyes he'd help me out as a combined birthday Chanukah present.

3rd post on this. My opthamologist has a better hypothesis. The tab 4 using LCD for the screen, meaning the tiny bulbs are fluorescent. The tab s and other higher quality models use tiny LED bulbs. Some people with eye problems see flurescent light better than other kinds of artificial lighting.

Don't know if this can be answered, but I'm looking for recs on a bluetooth keyboard. no usb dongle, 8.5 inches or bigger, non-cramped, responsive and tactile enough so that I can touch t ype and tell if I've hit the right key. No numeric keypad needed, the numbers in the top row are enough. I'd like del and backspace to be in normal 101 keybaord location. I understgand that bluetooth

Even if you don't use a Mac check out the Apple Bluetooth keyboard. I've used them for years and love them.

Anyone need a 10.6.8 (Snow Lion) disk? I have a spare. Family didn't communicate well...
