Con: No middle (wheel push-down) click
Pro: Everything else in life, also... the "Con" has it's reasons and is "made up for" (just keep reading)
Sleek, beautiful design. Heavy, durable build... as expected from Logitech.
Geared towards the laptop user, but nonetheless a desktop replacement. The only reason I say it is made with the notebook user in mind is because the size is slightly smaller. If you have unusually large hands, you may want to refer to the VX revolution (but I did read the reviews on that one, and it seems there are many hardware malfunctions with it). Anyways, when all mice that I have seen are "made for laptops," they are like smaller than a stick of gum. The VX nano is a "smaller mouse," but it is more than adequate in comfortability and functionability. Actually, it is marvelous. Logitech simply applied the compact mentality in a realistic way.
The nano receiver is uncanny. And I didn't pick up on this from other posts but, THE RECEIVER FITS INTO THE MOUSE ITSELF WHERE THE BATTERIES GO. The VX comes with a really edgy looking pouch. Just pop the nano inside the little door under the mouse, zip up and go.
I got really used to using the middle click button on mice for tabbed internet browsing, so the wheel took some getting used to. BUT, there is a good reason that we can't click it. The scroll wheel changes "scrolling textures." The VX comes out of the box with the wheel set to glide very smooth with no friction. I, in particular don't care for the super smooth scroll. When I started to use it, I thought to myself, "ohh, it's one of 'those' kind of mice." (Disappointed face). Then as I realized the middle click didn't respond, my wheel suddenly gave me a rubbing feeling under my finger as I scrolled. By clicking in the wheel, the user can change the scroll response from that "tak-tak" feeling to a nothing at all "super glide."
In return, I set the "forward" button (the top one of the two tiny buttons left of the left click) to "middle click", since I don't use the "forward" button on my browser nearly as much as "back." You may want to set the little "document flip" button to "middle click" since it is right below the wheel, but I thought I'd keep the new feature and try it out for a little. ("Forward" was more sacrificable). Furthermore, my "tabbed browsing" hasn't changed and definitely wasn't hindered by the new design and concept.
Finally, the software.... talk about versatility. Every button can be programmed, and if what Logitech suggests isn't good enough, you can set any keystroke/combinations to any button.
You can set different scroll reactions to different programs. For instance, an application that is more sensitive to scrolling like Autocad or Photoshop for zooming, you can set the croll to be less responsive to those programs only, so that you can be more accurate in your movements.
Gamers! The mouse and it's software automatically recognizes when a computer goes into a full-screen game mode. You can disable what the mouse does while playing a game. For example, the "document flip" button will pop-up a window that lists opened windows. Well, the Logitech software enables you to prevent any such pop-up only while experiencing a game.
They really have thought of everything with this mouse.
A review is supposed to either keep people from making the mistake the writer did, or encourage the reader to enjoy what a value he/she found. This mouse is a gem, I hope you readers hop on this deal.
