Cons: price is real hefty, lacks some high-end options like fast-big HDD, no Firewire.
This tablet is really the only true competitor to Fujitsu's long-time reign as tablet leader. It has a rich feature set, brilliant LCD display, and the processor power to exceed Fujitsu's latest offerings. Of course, the true utility in a tablet is the software, and Windows XP Tablet PC edition more than handles the job of capturing pen taps, clicks, and sketches (handwriting, lettering, or drawings).
As a portable PC, however, it is an extremely pricey solution. The largest hard drive is 80Gb -- for a laptop that is about the max -- but the rotational speed is 5400 RPM. No doubt this saves power and generates less heat, but the speed hit is significant.
Also significant is the cost of RAM upgrades for the unit. Two sticks of 1Gb RAM will set you back another $1700 over the sticker.
Getting past the price premiums, though, it's easy to see that the M200 can be a replacement PC with a decent docking station. You'll miss the Firewire connectivity, but the USB 2.0 ports are available and it does comes with an SD card reader in the unit itself. Nice.
With the WiFi radio, built-in Ethernet, and built-in modem, there's really no reason why you can't connect on the road. You can opt for the 802.11b or 802.11g radio, but opt for the 11g and get the 54Mps instead.
I was a big fan of the Portege 3505 series from Toshiba, and this tablet marks a nice upgrade from that series. Adding WiFi, SD card reader, faster processor, and more RAM options makes this the tablet if you need one... and have the bucks for it.
