Microsoft Bluetooth Mouse - Performance

While the Bluetooth mouse takes advantage of Bluetooth's convienience and security, Bluetooth
seems to be be it's stumbling block when it comes to speed. 

Because Bluetooth can offer a huge bandwidth increase over regular RF connections, I fully expected an ultra-high refresh rate.  At the very least as fast as a corded USB mouse.

Unfortunately, the MS mouse doesn't make full use of the bandwidth offered by Bluetooth connectivity.  If this was the case, we would have seen a straight 1 KHz connection, which would have been sweet.

As you can see here, the mouse's refresh is a little strange.  It peaks briefly at over 1KHz before
returning to 90Hz, which seems to be its "real" average.  Still, at this speed, I found that the mouse was quite good for most games like UT2003 and Jedi Knight II.  A solid performance all


In order to conserve battery life, the mouse powers down when it's not in use for a certain period of time.  This results in a pause when you want the use it again since the optical sensor has to wake up from "sleep mode".  A little bit annoying but the battery life benefits seem a little more important.

This unit also carries a $85 price tag (around $75-80 street), which is quite a bit more than most people want to  spend on a mouse.  However, in that $85, you also add Bluetooth connectivity to your rig, which costs quite a bit in itself.  The cheapest Bluetooth adapter I could find on Pricewatch came to $29 and most quality, name-brand ones are quite a bit more.

Logitech MX700 - Aesthetics and Ergonomics


As with the Microsoft Bluetooth mouse, the MX700 is also a looker with its metallic silver paint job and subtle smooth curves.  Personally, I prefer the look of the deep blue on the Microsoft Bluetooth mouse and its transceiver to their Logitech counterparts.


The MX700 has the Microsoft mouse beat when it comes to comfortablity though.  My hand feels more fitted to the MX700's grooves and it seems like a slightly more natural palm position.  As with the Microsoft Bluetooth mouse, left-handers will have to look elsewhere.  Logitech MX300 uses the same optical technology but lacks the MX700's sculpted ergonomics and extra function buttons.

Speaking of the function buttons, there are five of addition to the usual three, making for a total of eight, that three more than Microsoft has.  All of them are programmable but the pre-programmed functions seem to be pretty useful.  The side buttons do Internet Forward/Back while one of the top buttons brings up a menu simliar to what ALT-TAB gives you.  Again, being the lazy bastard that I am, I found the side buttons slightly inconvienient and I can't think of a reason why Logitech would move it from below the thumb, as seen with it's Wireless Mouseman Optical to above the thumb.


Along with the scroll wheel, the two function buttons on either end of the wheel also scroll up and down.  Depending on how many lines you set the scroll wheel to cycle through, the function buttons simply scroll faster.  These buttons are in a slightly inconvienient spot as well,  requiring some finger acrobatics.

The scroll wheel itself is leaps and bounds over Microsoft's offering in that it's extremely smooth and doesn't have any annoying clicking noises.
