The HP ProBook S-Series is the latest laptop for the 9 to 5, suited and booted crowd. Billed as ‘business laptops’, the ProBook S-Series will be available in 14.1″, 15.6″, and 17.3″ versions.

Whichever version you choose, you can opt for either an AMD or an Intel processor, SD card reader, optional Blu-Ray drive, and HDMI out. The 15.6″, and 17.3″ versions also come with a numeric keypad (why exclude it from the smaller 14.1″ model we don’t know). Unusually for HP, the HP ProBook S-Series also offers you the choice of having Linux pre-installed or Windows Vista when the laptop ships. You also get an ATI Mobility Radeon HD 4330 graphics card thrown in for when you have ‘down time’ at the office and want to get your DOW 2 on.

With prices starting at $529, you could say that the HP ProBook S-Series screams upper-midrange, which, funnily enough, is quite an apt turn of phrase for the business types who will probably go for this.

Release date unconfirmed but expect it to be well into June before the HP ProBook S-Series laptops hit our shelves.
