Looking forward to reviewing a new convertible tablet PC

I'm looking forward to receiving a convertible tablet PC so that I can review it and blog about my first impressions. I don't want to give away the details, so you'll have to stay tuned.

By means of background, let me list a few of the convertible tablet PCs I've used/owned:

• HP EliteBook 2730p tablet PC
• Lenovo ThinkPad X200 tablet PC
• Lenovo ThinkPad X41 tablet PC
• Fujitsu Lifebook P1610 tablet PC
• Fujitsu LifeBook T3010 tablet PC

I have yet to find the "perfect" convertible tablet PC. If I could design a tablet PC, here's what it would look like:

• It would have a 12" or 13" screen offering dual-input modes (a Wacom active digitizer and a capacitive multi-touch touchscreen)
• It would be as thin and light as a MacBook Air (but it would have a removable battery). Maybe as thin and light as a ThinkPad X300.
• It would have a full-size keyboard like that found on the Lenovo ThinkPad
• It would have an illuminated keyboard (or at least have a pop-out LED light like that found on the HP EliteBook)
• It would have a dual-input screen that includes a Wacom active digitizer and a capacitive touch-screen
• It would weigh less than 3.5 pounds

When will someone make a convertible tablet PC that includes all these features?
