A long time ago there was post with various solutions to the need for a stand when typing, well I think I may of found it, the Bookchair from
www.bookchair.com, Amazon etc. I got the idea when I saw one of those little novelty chairs for cell 'phones and remembered seeing something for cook books, a month or two later and a few odd conversations in bookshops and I finally found them in Borders. Sadly they didn't have the "Mini" at the time but Amazon did.
The "Mini" in the attached pictures is the perfect size for the X50/X51 with or without case and with any size battery - it's a deck chair for books so it folds flat and it has those little tabs at the front to that hold the Ax in place, so if you're typing on a train etc well you get the idea :) I've tried it out and it makes typing alot easier than the stand that comes with my TO BT Keyboard and so far I'm quite impressed.
