But to be serious. There will be at least 60 to 80 % of the Customers, which don't even know anything about positive or negative Accel, and some of them already played with a Laser of the first Generation build in the very first Lachesis for example like a young God, without noticing anything wrong with the Sensor until somebody told them about it.
I mean, sure it would be cool to have a perfect one build in the Taipan, but we'll see.
Looking forward to further Results EnthusiastR. thumbsup
Because of Quality the Taipan looks damn fresh and a excellent Sensor would be important and the cream on the Cake ofcourse.
Well the first generation Lachesis was bloody brilliant when kept dust free and used on a hard surface as soft surfaces made it jittery when clicking the buttons. The tracking itself was amazingly precise with absolutely zero positive acceleration and no negative acceleration up until very high movement speeds. To resolve the clicking induced jitter on soft surfaces, they added that dynamic DPI scaling later on in some Mamba firmware update and included it into each PTE mouse they released since then... basically crippling their precision.
Anyways people should realize this: If you want the highest precision at higher DPI settings without correction, jittering etc. the PTE sensors (without that dynamic DPI scaling activated) are the way to go as they are unparalleled to date. But only in conjunction with a hard surface. That's what their marketing strategies should have mentioned in order to avoid that bad reputation. These sensors are god knows no way perfect. They have their issues like z-axis tracking, making them prone to soft surfaces or vibrations and are also more prone to dust (so you have to clean them from time to time). But used in the right environment they are - and I have to repeat myself - unparalleled in terms of precision.Which brings me to the Taipan:
This one review mentions a little negative acceleration. Now when you remember the performance of the ADNS-9500 (and 9800 I guess) it was that artificial nonlinear positive
acceleration that was bugging most people. Yes the 9500 had negative acceleration in combination with some surfaces
, which means they couldn't track them well and therefore you didn't have to move your mouse too fast in order to make them reach negative acceleration. Coupled with the proper surface negative acceleration didn't show at all until extremely high movement speeds, you would never achieve when gaming. So the 9500 never had a persistent negative accel issue - it was just in combination with a few mousepads and as far as I know the 9800 resolved the issues with some of these pads.
Nonetheless both of them had persistent positive acceleration no matter on which pad they were used on. So to remind you not one from the people who had the Taipan review units, was stating that it had any positive accel. In fact only the one review so far mentioned any acceleration and this was about negative accel
and he specifically tested for these issues. Now what does that tell us?
As the ADNS-9818 used in the Taipan is still based on the 9800, he might have tested the mouse on one of those surfaces that might not mate well with that kind of sensor, so this behavior would be expected in that case. The other thing is that he didn't mention the method he tested for the negative acceleration exactly. And I'm pretty sure he did it like the user posting in this thread before, meaning he did a fast swipe in one direction and a slow swipe back. So he could have done that fast swipe so fast that he surpassed the perfect tracking speed of that sensor. And voilá: negative acceleration (as expected). And as I just said coupled with a pad the 9500 & 9800 are known to track less than optimal and you hit that perfect tracking speed barrier even faster... so he could have noticed some negative acceleration without even having to try too hard to swipe the mouse extremely fast.
So what I'm trying to say here is that nothing is lost yet. The persistent positive acceleration was the thing that was bugging these sensors (9500/9800) and no one from the testers mentioned these issues with the Taipan (actually some even specifically denied it). So while I'm still skeptical until I hold one of these in my own hands I haven't written them off yet and neither should you until there's actually someone really reporting and proofing that there's positive acceleration.Edited by MONVMENTVM - 6/28/12 at 3:58pm
