For the last month I've been doing a contract at Canary Wharf for HSBC. In an effort to minimise the amount of stuff I carry, I've just been taking my iPad into work with me. I've really missed having my home emacs environment available.
Last night I was thinking about this and I decided to get a bluetooth keyboard I could leave at the office. I can ssh from my iPad to one of my Amazon cloud instances, and have an emacs / development environment set up there. Consequently I bought a Cerulian Technology Mini Wireless Keyboard. It was really easy to connect to my iPad, but the keyboard is quite cramped to type on. The tab key especially is miniscule, so not great for Python coding. It's still the first few hours of use, but I'll keep using this and see how well it works over the long term.
