That does NOT mean that it isn't there. There has been a lot of work hiding the flaws in the PTE, but if you just use a raw firmware like the earlier 1st gen Mamba firmwares you can absolutely wipe the floor with people in specfic cases with PTE mice. They are using the Doppler effect and operate differently than laser-illuminated sensors like the 9800, so a very different technology.
Optical beats the **** out of laser mice though in every category except for LOD, which itself has been drastically reduced in modern optical designs and is hardly an issue now.
I agree and disagree with you on certain points. The 9800 isn't a great sensor. I actually prefer the 9500(sensei), as I've had less issues with them overall, but I was one of the sad early 9800 adopters that had to deal with the floating cursor issues of the early firmwares.
As far as the PTE goes... It has issues. I personally hate the way the cursor feels, but the other negatives far outweigh the positives. It does have a great PCS. It also has no acceleration or prediction. That's great. Unfortunately, it is also the pickiest sensor on the market when it comes to debris. If you have anything on your mouse pad or god forbid, the sensor itself, kiss the cursor control goodbye. Then there's the hyper sensitivity to EVERYTHING. They've used dynamic CPI(a total performance nightmare) to hide this, as well as the z-axis bug, but if you have loud speakers, a sub woofer, a twitchy leg, or a habit of drumming on your desk while playing, sit back and watch the cursor walk it's way up the screen. This mainly bothered me when playing games where my mouse hand had to stay still for some period of time. I'd have to move the mouse to regain control over the cursor and correct the location. Then there's the z-axis bug. This was the major killer for me, but I'm a mid-sense lifter, so it is the perfect bug to piss me off. Finally, the failure rate. Three of the four PTE mice that I own have lost the y-axis completely. I might be alone on this one, but it seems to be a popular issue on RAT mice. Some say a deep cleaning will get the axis back, but I've just called and had the mouse replaced.
After fighting four mice with this sensor, including a RAT7 with the newer revision, I've writtin the PTE off completely until Philips completely starts over and stops putting a bandaid on a gaping wound.
