What PDA/Pocket PC has all these functions at a good price? - pda keyboard software

With a view to a portable device that has all the following features to buy. The upper part preferably no more "in line" because they are often about my point of view price of $ 350.

Minimum:
Hardware QWERTY keyboard (touch screen, for example)
Wi-Fi capabilities with a good browser
Offers software compatible with MS Word / Excel
Reliable battery
SD Memory Card
supported by the online community with downloadable applications

Ive seen many models of PDA + cell phone that would be great, except I do not plan to do to use the phone's features, and it usually adds $ 100 + pricetag. Something that was top-of-the-line 1-2 years ago so to be in a situation as a unit of ADP today's standards.
