Looks like HP's web monkeys are filling in the product pages for those unannounced Mini 1100s we spotted earlier -- spec pages for the 1133CL, 1135NR, 1140NR and 1141NR have been posted, and those rumors of an ExpressCard/54 slot are apparently true. It sounds like the 1141NR is the Vivienne Tam edition -- it comes with a "Vivienne Tam sleeve" -- but apart from that and Bluetooth in the 1135NR and 1140NR, they've all got the same 10.1-inch 1024 x 576 display, 1.6GHz Atom N270, 1GB RAM, 60GB drive, and three-cell battery. No idea why HP's got so many different confusing model numbers for what seems like the exact same product, but we're guessing we'll find out more soon -- hopefully there's a bit more sense behind this silliness than with the Eee alphabet soup.
Update: HP's told Lilliputing that the ExpressCard listing is a mistake and that the 1100s are just minor variations on the 1000s, but the entries are all still up with no changes. Guess we'll wait and see when these things go official.
