+1 to that too.
t60 convertible tablet laptop is just that ...fab.

And yeah the price tag issues which have been mentioned...
yeah well...
a desktop is cheaper than a laptop which is cheaper than a tablet which is in turn cheaper than a convertible.
Also considering guts...oomph...computing power...what have you....essentially all the goodies..it's always been about what could be crammed inside the given space and still be at the edge of comfort...regardless of what the form factor was.
Some did / do it better...some did / do it worse.
For those thinking that a convert doesn't have the ability to accomplish serious work. I beg to differ. Either you haven't used what I use currently and /or had a bad experience with a tablet or convert. in the past....I had a few of my own...back in the early-early 2000's....the tablet pc's and convertibles just weren't anywhere near.
The only drawback today compared to then is that the screen real estate and screen res. was killer on some (acer travelmate c100, c300, portege m200, tecra m4, m7..absolutely a joy to graphically work on....both brands which I still use for sketching, painting and base initial work on before transferring to my portege m780 or x230...) ..they just don't make good screen sizes any more..let alone screen resolutions...I mean it is hard to beat the joy of a nice res like 1400x1050 SXGA or higher even ....on a penabled laptop or tablet..but yeah...they don't make them like that anymore sadly.
That's why I like the older convertible tablet/ laptops for graphic work (at least initial... if not almost all the way to finished state..before transferring to a more mod system for completion...)
The only thing I don't do on my m780 or x230 is serious gear-wrenching work that anything less than a desktop or desktop replacement killer normally couldn't do. Then I simply transfer said work to the more capable system for finishing. But those kinds of programs are few and far between (so far..as some serious progs get heavier and more consumptive in the future ..as the nature of things is wont to do..I'll slowly relegate less and less to my current graphic beasts ..and hunt down the next "current" model in the future.)

For me...work-wise I've had my bad experiences in the early years...but I quickly found what makes and models I liked and needed to get the job done ...
So yeah...
In the end it depends on the usage...the need.
A desktop is great ...but uncomfortable and not portable.
A laptop is great ..but doesn't have the guts of the desktop nor the uber comfort and tactile interface of a tablet sittin' on the couch.
A tablet is great...but doesn't have the desktop guts and is pitiful to type on unless you have an external keyboard...
Depending on the make, model and year ...a convertible can fit at least the comfort of the tablet and the convenience of the laptop ...but still...the computing power winner goes to the stationary giant box under the desk ...or...the desktop replacement killer laptop.
For the time being....

It's been mentioned before....and it is sound advice...
research, research, research...
find out what specs you really need 1st.
2nd...don't buy the latest..buy an older model..try out what you "think" you want . If it appeals to you ...and subsequent newer models by the same producer offer nothing but a better experience....then there is your answer for the potential for a future investment.
