I use gmail because it gives me access to my emails wherever I am. I spend a lot of time on client locations and systems, and very few offer me the option to use my own laptop on their network. I am mostly forced to use the systems available. This isn't generally problematic, because they all have some sort of browser and an internet connection.
However, i have no control whatsoever over the browser or version installed on those systems, I just use whatever is available to me.
As long as I get off with some sort of warning that I'm using old hat I don't really care, but if Google insist I use the latest and greatest to access my email and do searches I will quickly be forced to use services from another supplier.
Maybe it's just an opportunity in disguise.
