I’ve been using the official GNU distribution of Emacs for Windows for the last few years and am very happy with it. Well, usually I am very happy with it until someone sends me a 25GB log file I need to analyse and the 32 bit Emacs refuses to play when faced with the enormity of the file in question.
For those who aren't aware of this yet, there is an Emacs Stackexchange site that's currently in beta. I'd like to encourage everybody to take part in it so it can become a viable site on the Stack Exchange network.
Announcement on the emacs-devel list. Fingers crossed that 24.4. will be out in a few days as mentioned.
We have an early 2008 MacBook "Blackbook" that is still working perfectly well and does everything we ask from it. It's one of the reasons I love Apple hardware - it's well engineered and works without a major fuss. Obviously we're not playing games on it but it's perfect for us to use for tasks that need a bit more power or typing than you'd want to do on a tablet. It's also perfect for doing tasks that I want to use a separate computer for, like online banking.
