I've been watching these on the Lenovo site.
Feb RRP $399
April RRP $406
June RRP $604
Just noticed that Lenovo has them on "special price" of $399 at the moment.
Looking at JB HiFi they have them on "special" for $399 plus a "free" Lenovo Smart Clock RRP $99.
Not a bad deal if you can make use of the Smart Clock or flog it to recoup some $$$ :)
Love mine and it meets 90% of my (meagre) needs. :)
