My white PRS-T1 has a Decal Girl skin (in
Tangerine Floral) to get rid of the glare, and for awhile I used a PRS-350 white sleeve from Case Logic, but it was a tight fit and I got tired of wrestling with it.
I do prefer a case-less reader, but my purse is dangerous territory. I tried the regular Sony case at Target, but felt that it was uncomfortable to hold - the tray digs into my hand.
So I took a chance and purchased a
mCover for Kindle Touch in Aqua, for $7.99. I'd call it more of a Robin's Egg Blue, but it is still a nice case, with a nice, pocket, and an elastic band to hold it shut, and keep the cover from flapping. It comes in several other colors.
Here are pictures of the T1 in the case, and with my
preferred book light. The Kindle Touch is a bit wider, but the friction of the case lining keeps the T1 secure - no wiggling. And the corner pieces don't obscure the buttons like most of the other Kindle cases.
