There's something almost ... appealing about how ugly they are (referring here to the old beige one with the square nose and the little metal nameplate). Looks like something my dad would design.

WIRED MICE 4 LIFE.

*In a case of 'Logitech hates Vista users or old customers', removing the support for their older mice from their Vista compatible driver has left anyone with an MX700 stuck on XP or hacking together a Vista32 workaround. Vista x64 has no such workaround so your 8 button mouse** only has 5 buttons visible to Vista and you can't rebind them to keyboard modifiers.

While the gamers' favourite (back when it was reasonably new) MX700 and wired brother, the MX500, are both out of luck, Logitech would be more than willing to sell you a completely-compatible-with-Vista-x64 MX518 which looks identical to the MX500 but with some new paint and a slightly better sensor. How about a G5 Laser mouse? Similar body but with new internals and again Vista support for configuring buttons and all that jazz. Some might say they're using the Vista driver change to force upgrades for the folks who only get a new toy when the old one breaks. Unfortunately, it's a tactic that works. I couldn't find an alternative brand that make a mouse with similar functionality and form so downgraded to a wired edition of the mouse I already have to unlock the functionality of it under Vista x64.

**Yes, I do find it useful to have that many buttons. Several years of shift and ctrl being on my right thumb in games and even the desktop is habit forming (in fact I don't know how I'd be able to manage action bars in WoW without it) and moving less used but important functions like 'bring up full map' and 'torch on/off' to above/below the scroll wheel keeps my WASD space clear in more button heavy FPS (leaning round corners being the main culprit for cutting down on the natural selection of left hand keys available without glancing down).
