Currently, Dell has a sale on both of these mice making them both less than $35.00. However, I don't know which one to get. Really, it comes down to size. I might be carrying this around campus sometimes, and the main purpose would be for CAD. So is it better to get a full sized mouse, or a more portable, but smaller model?
Yes, I went with the M305 because it was smaller and hopefully more portable. So far its great.
Those are good prices! I live in Canada though, and the cheapest I could find was $35.00. Do you know if Best Buy prices are the same in the US as in Canada? I kind of doubt it.
I don't think the pricing would be the same, if it was that would be a good thing : )
Here is the M505 pricing at Canada BB: http://www.bestbuy.ca/Search/SearchResults.aspx?path=ca77b9b4beca91fe414314b86bb581f8en20&q=logitech%2520m505&sp=BBY_en-CA_Site-WideSP&Category=Entire%2520Site&pcname=MCCPCatalog&AllowSecure=True
