I thought some people may be interested in finding out how the MX Rev compares to the MX1000 (I've had the MX 1000 for almost 3 years now and was a big big fan!)
My MX1000 middle button broke recently so Logitech replaced it with a new one but in the few days "downtime" I just had to have a decent mouse so though about selling the replacement and buying the next one up, the MX Revolution.
PCWorld had it for £55 so I went down and picked it up. Installation via Setpoint is as easy as always with logitech stuff, everything works and uBeroptions installed perfectly too allowing me to customise the freewheel button and other stuff too.
The first few days were awkward - I was sure the MX1000 felt more accurate in motion and detailed work but in fact they're almost the same - it's the MX1000 that I was so used to, the shape and feel etc that it felt better but the build quality of the Revolution just outranks the MX1000 in every aspect - the wheel feels mechanical in ratchet mode compared to the loose plastic feel of the MX1000 and the freewheel is just amazing in apps like Google Earth or "random image" threads on various forums
I actually returned the revolution on the 2nd day because of the accuracy mentioned above but using the MX1000 again made me want the Revolution back, I found out the reason it felt less accurate was because the laser is actually at the opposite side of the base compared to the MX1000 which I was used to - simply adjusting my mouse usage to the revolution resolved this issue so I returned today and bought the Revolution a 2nd time round (lol).
The Revolution is a lighter mouse too so better in games where fast movements are not as fast on a heavy mouse as the MX1000 - it also sits more glove-like in your hand - it's more low profile than the MX1000.
Overall the best Wireless mouse you're going to get! no response lag (same with mx1000) but many people will be put off by the price tag (£60-£70 retail, £55 on offers) whilst the MX1000 is £35 now on some places.
Highly recommended mouse! the packaging is also very slick.
I give it an 8/10 only because the battery meter in SetPoint is not as accurate in "days left" as I would like but other than that it's a comfortable and precise mouse after you get used to the shape of it!.
