Summary: Definitely not your average mouse. Works well with Windows 8, although it took some experimenting to find finger motions that worked consistently. After a while, it felt completely natural and I stopped thinking about it.
Pros: Convenient, lightweight, and reliable. Has an on-off switch to conserve batteries.
Summary: The mouse is well built but the software driver is terrible. The scroll responsiveness is terrible, right click or left click work when they want so much so I just basically used the mouse as a backup, but do yourself a favor do not buy this.
Summary: I swear by Logitech products. Since my 1st computer I bought, all mice and keyboard purchases were Logitechs (currently sitting at 9 Logitech products). This was something new and I was curious how a touch mouse would feel when using Win-7. I regret the purchase. I was 15 minutes late to work today.
Summary: I thought these were pretty cool looking when the came out last year, but the price was kind of high. Picked it up on sale for $25, it's pretty good. Nice and light, cordless, comfortable and a good set of touch gestures. The software is easy to use too. The software gives a decent amount of customization, I do wish I could swap the direction I swipe my finger in to scroll up and down (invert it I guess).
Pros: Light, responsive, comfortable, has touch, software is easy to use.Good price at $25-$35.
Cons: Non sale/MSRP price is way too high at $70. You can just get an Apple Magic mouse at that price that uses more premium Glass/Aluminum materials.
Summary: I saw this mouse in the store and decided to give it a shot. I am a software engineer and use this mouse daily. I am running Windows 8, 64 bit and have the latest drivers. My biggest problem with the mouse is scrolling. It just doesn't respond well enough for me. End of the day, I need more responsiveness and will be purchasing a different mouse in the near future.
Summary: The design is great and still looks good after months of use. Unfortunately it is lacking in some ways. My main complaint is the lack of drivers for OS X and Linux which makes this mouse less practical than a cheap generic mouse. There is no reason to use it instead of a touchpad on a Macbook as gestures don't work, and the lack of drivers on Linux means that it can't be configured at all (even if you have gestures enabled, as it won't affect this mouse).
Summary: I am using it with Windows 7 and I find it slow on scrolling up or down + at times the mouse will generate commands that you are not seeking for example occasionally when scrolling up or down a page it will produce various windows that are not requested.
Excerpt: The key to enjoying this mouse is learning the touch stokes and understanding Windows 8. I purchase my first T620 for my Windows 8 upgrade on my desktop computer and after using it for a few months, it was time to pick up another one for my Windows 8 ultrabook. The quality and precision is excellent, the best I’ve seen or used to date.
Summary: The key to using and enjoying this mouse is learning the touch strokes and understanding Windows 8, I purchased a T620 for my desktop when I upgraded to Windows 8. After a few months of use, it was time to buy another for my Windows 8 Ultrabook. It’s important to learn the touch stokes to enjoy the mouse or you will need to open the software and turn off the touch features and use it as a standard mouse until you do.
