I would definitely recommend a multitouch / pen-enabled tablet to anyone, corporate or consumer, who has the funds and sees value beyond bottom dollar sticker price. Convertible and slate tablets have been around for a LONG time, but as fatpat mentioned, they have always been rather niche primarily because of their price, but also the lack of capacitive touch held things back. Tablets range from slow-but-efficient ULV models to just-as-powerful as anything else models.
The caveats for a tablet purchase: Are you fine with a 1280x800 resolution, a 12-13" form factor, and an integrated graphics card?
Despite what was written twice above, do NOT go for a HP consumer-line tablet (TM2/TM2T), or HP consumer-line anything for that matter. They are subpar and have been for many years now.
If you're looking for good touch, your choices are limited to recent releases. I wouldn't recommend the older devices despite their claims since either it was at the expense of the pen, or the entire system was just wonky.
Since you're looking for a convertible, and I'd wager a guess that you don't want to sacrifice much computing power but still want battery life and mobility, you're looking at:
Lenovo X201T
HP Elitebook 2740p
Toshiba M780
Fujitsu T900
Panasonic Toughbook C1
They tend to start decently equipped with i5s around $1800 - you might need more ram though - and max out with boatloads of options (dock, battery, more ram, faster hdd, etc.) around $3000. Some might balk at spending $2000+ on a laptop when you can run to newegg and pick up something that "works" from Newegg for $699, however, the added functionality from the pen/touch, coupled with the superior business-class build quality and extended warranties make them worth it.
If you want additional thoughts:
Lenovo: The thinkpad motto of continual blandness is just ridiculous so I cut it out immediately - despite that, it's an extremely attractive device functionally.
Fujitsu: I've heard their support is pretty lacking and their build quality has been dropping. They used to make REALLY good products, so lower than really good is still good... right?
Panasonic: I couldn't stand that cheesy rubber strap on the Panasonic C1 - I think I could have grown to love the odd styling. I loved the dual-battery-bays.
Toshiba: Best-priced with a fully equipped pre-config i7 and 4GB ram, and 7200rpm hdd @ $1800 msrp. Touch support, but not multi-touch. 4.5lbs and 2-3hrs battery life (6-7 with poorly designed thin-slice.) I've had a M200, M400, and M7 in the past - all Toshiba convertible tablets. They were always great workhorses once they got past their first warranty call

If this was styled like the M200 I probably would have leaned in this direction.
HP: Actually a classy-looking machine, great build, 3.8lbs and 3-4hrs battery (9-10 with well-designed thin-slice.) Slightly less powerful pre-config models (i5, 5400rpm drive) but a SSD fixed that all up!
//Bit too obsessed with the form factor, sorry. HTH!
