Palm Portable keyboard How Useful?

[RichardA]

As many of you probably know, Palm was offering either a $50 rebate or a Palm Portable Keyboard (a $79 value) or $100 worth of software as a rebate when buying a M130.
Are any of you currently using the portable keyboard? Is it worth it, or should I just go for the $50? I am not a student, I work in an office and do a lot of my writing on a laptop.
In the past I have not done much word processing on a PDA, but the M130 does come with Documents to Go, so it's more likely, or easier, to create Word documents. I don't travel much in my current job, but that can change in the future and I do have a long commute, so I can see myself using this item (as long as I have a steady surface). I also may take some classes in the future, so this might come in useful.
Any advice is welcome:)

Sounds to me like you want it, but you need the ok.

O.K.

I have one and I love it. I have a desktop at home and a laptop at school, I'm a teacher. But if I have a meeting or need to write things down in my classroom the keyboard is great. The keyboard let's me type where ever I want. Sometimes I take plane trips and I love it then too. Plus the oohh factor is pretty cool. I just took a Master's course and was about to give my teacher a leeson in Palm's (I think that helped me get an A in the course ;) )
