At work I use Windows / linux, but about a week ago I switched from using a MBP as my primary computer at home to a Transformer Prime.
Impressions so far: it's awesome. Consuming is much better, which is most of what I do at home. Most producing I've done lately has been of the pure text nature (emails / blogs etc). The onscreen keyboard is mostly find for this, and if I need to bang a lot of text out I can attach the keyboard.
I'm a bit overwhelmed with work work atm, but when that calms down I'm keen to try AIDE[0], as well as look for a more light weight editor for python / html hackery that can connect via ftp/ssh or similar, and play with developing web apps that way.
I'm surprised they're on HN but I have a (geeky) friend who do most of his work on an Android tablet so that his "computer" is always on and ready. That makes a difference when you run more than one time in more than on place and you spend a lot of time with your customers too.
