Without further ado, I therefore let me come to view both mice. Here is my comparison:
Style:
Surely a matter of opinion, but the MS5000 doing besides the Nano has significantly more ago. The white-silvery remote from the black housing keys act "chic", especially if you want to customize their desktops in the Apple design. From experience, however, prompted by the concern that the keys of the MS5000 wg. its bright surface could be quickly unsightly.
The Nano is rather plain-discreetly in very dark colors, on closer inspection, however, like the quality and visually better mouse wheel.
Winner: Draw
Processing:
Mixed picture. The just 20EUR surcharge for Nano are certainly somewhere better processing in particular the mouse wheel owed. Here the MS5000 really can not keep up, the wheel is for my needs too low in the mouse is at unoptimaler hand positioning on the mouse also sometimes very hakelig. The harder pressure point in comparison to the Nano is easier to handle for me, however.
The reverse button is kept technically and visually very simple at the MS5000, here the Nano impresses additionally with an additional forward button.
The MS5000 but saves himself in this category of the essential key tone more pleasant. WHILE the Nano produces an audible clicking sound as good with every click, the MS5000 is nearly silent. For me, this point was a key selling point for the MS5000 as the click just extremely disturb when working at night.
Winner: Draw, possibly a slight advantage for the Nano
Installation and Operation:
Here the MS5000 dominated by its modern Bluetooth technology. Commissioning under WinVista went with my Lenovo X41 TPC unceremoniously unless you work outside of Windows, of course you have to change to the TrackPoint lack driver.
The Nano uses the familiar USB dongle technology, even though the adapter is really small now.
Will you therefore operate the mouse only on a notebook, the choice is easy. If flexibility is required on several computers, recommended probably continue rather the quick-change USB adapter.
The lack of software for the MS5000 not struck me negatively, because I mean mice anyway be used only as a plug-and-go and my OS fully Mülle reluctantly with these new programs.
Winner: MS5000
Price: MS5000
Winner: MS5000
Keep I ultimately the MS5000, because it is better suited to my needs and also still is almost available at half the price of the Nano.
