Does anyone in the NYC area have a pre-2000 PC with CRT I use to do some input-to-screen latency measurements?

Also, does anyone near NYC have a phone I can use for latency/responsiveness benchmarking, esp. an older iPhone?

I've started doing basic latency measurements on phones and haven't found and iPhone that's slower than any Android phone.

I'm curious if an iPhone or iPhone2 is quicker than a modern Android phone at scroll and/or tap responsiveness.

I've started measuring keypress -> USB latency with a logic analyzer and I'm seeing some measurements in the 20ms to 30ms rangepic.twitter.com/nzUPYMS2rn

Is this plausible? 20ms to 30ms for a keypress seems absurd. OTOH, it's consistent this person's experimenthttp://forums.blurbusters.com/viewtopic.php?f=10&t=1836&sid=080b1b6a517ed1eb6988627c48da080c&start=10 …

They start measuring from internal switch activation and I start when the key moves, so that could explain the 10ms difference.

Also, does anyone in the NYC area have an "interesting" keyboard I can borrow to test?

So far, I've tested a couple gaming keyboards and a bunch of other "normal" keyboards. The gaming keyboards haven't been faster.

On the other hand, perceivable 'lag' might have improved a lot on Android:https://trends.google.nl/trends/explore?date=today%205-y&q=iphone%20lag,galaxy%20lag …

I think it's gotten a lot better, but according to the preliminary measurements I have, Android devices (that I have or could borrow) are still slower. I'll try to write this up soon, but I've been busy with job search stuff.

@synotic and I were working on Etsy's mobile web tuning smoothness of interaction and iPhone 4 was waaaay smoother than android -
though hilariously our "crappy" android 1.6 virgin mobile phone we got was often smoother than our Nexus S?
