decided to jump on the bandwagon and build a lightweight tablet for looking up IMBD when me and my girlfriend have an arguement over who some actor is and what film theyve been in.
Picked up a eee701 on ebay with some case imperfections (glued on stickers) and a keytop missing
removed the LCD lid from its hinge covers and chucked the metal hinges
Plastic welded the LCD back bezel to the base top bezel (still gotta get some modelers putty to fill up the imperfections and sand it)
used an ebay touchscreen kit (still have to add in a hub to regain the webcam)
extended the LVDS cable:
i bought two 701 cables cut a connector off each end and joined them in the middle just to halve the amount of teeny weeny little cables i had to extend) im sure its been covered here before but the wires in the LVDS cables are tiny little coaxial cables, youll need to use a not very sharp at all razor blade to scratch up the outer coating around an inch from the end of the cuts untill you can pull it off cleanly, then unwind the shielding conductor from the inner cable, and twist it so its nice and out of the way, then using the same method, remove around 5mm of the coating from the inner conductor, then using a multimeter set to continuity mode, test that the two conductors (shielding and inner) are not connected, otherwise whatever voltage is applied to the inner conductor will go straight to ground your eee wont start up and the Vreg chip gets hot enough to leave a nasty little rectangular burn on your finger when you notice its hot and just have to see how hot. then solder the matchin inner conductors together from each cable, join all the shielding, and insulate everything - this is a **** of a job, i did it over a couple of days so i dint get frustrated and FUBAR something.
re assemble and viola.
only problem is im new to linux, ive figured out how to get the advanced desktop and how to make the touchscreen work, but for the life of me i cant get any linux onscreen keyboard to install! can anyone help me out? - if not i may just have to put XP on, i think ive got a Nlited Xp install disk for the 701 here, but id rather not
and here are some pics of the eeetablet as it stands:

May this thread be of any help?
You may have to bite the bullet and install a more up to date distro of Linux to get a decent on screen keyboard.
That mod looks pretty slick though

that looks nice! 
i like that it looks like a real tablet and not a convert !
good work:) !

damn, i just let the magic smoke out of my screen, i pulled the eee apart to hook up the hub and camera and spare USB ports, when i plugged the screen back into the inverter board the cable slipped half out of the inverter board - got a vinyl/amonia type smell and a blank white screen, reseating the connector still only results in a white screen 
looks like its off to ebay for a replacement

Haha is everyone named Michael making a tablet nowadays? I mean I did an I'm Michael.
Also, may I ask if my tablet mod inspired you at all? It's got the same general idea of using the original screen bezel flipped back and facing up right where the keyboard was before. Did you keep the back of the screen assembly or did you take it out? (the part wih the shiny ASUS logo)
If you use the official asus xp disc then you'll have roughly 800mb to work with on a 4g after firefox, flash, and and nod32 antivirus are installed (thats from my experience). If you do end up using xp make sure to put a gig of ram in it or it will be pretty slow. The virtual keyboard I used was called freevirtualkeyboard. It's portable so you can just have it in the startup folder or have the .exe on your desktop. No installation required.

i cut the area out behind the screen (about 15mm smaller than the screen itself), then removed half the thickness of the plastic left behind the screen to recess the screen and touchscreen a bit further in so it didnt bulge, this is where my touchscreen controller and hub are living.
no particular inspiration - i saw what others had done with making their own replacement bezels, and what some had done by flipping the screen and hacking away at the back of the lid, then kinda merged the two ideas to come up with mine - once i finish filling and sanding and painting the join it should look pretty close to a factory finish and in the end it goes together and comes apart just like a regular eee. im gonna buy another dead eee for a screen so i may re do the mods to the plastic bits and take some progress photos so others can follow what i did. if you can install a TS doing this isnt much different (just very fiddly in some places)

got a new screen, finished off all the wiring and re assembled, added the extra repositories as linked to above by "WegianWarrior", then tried to update firefox because a few websites were whinging about the old version, used synaptics package manger to install the asus eee updates for firefox and other programs - then firefox wouldnt run and threw up an error stating that my gtk+ version was 2.80 while it needed 2.10 (so not only windows software has infuriating bugs like that ,
now ive installed winXP on it - i must say the drivers for the touchscreen work WAY better in windows (although only 9 pt linearization, no 25pt) and the winXP UI is much better suited to touchscreen devices! just gotta get some modelers putty to finish off the joins now -
but im already looking at doing another tablet mod so i might try my luck selling of this one, my eee 1000HD is looking mighy tempting, although id like to do a full size (14.1"+) laptop, just have to find the correct one to start with ( i like nice squared off edges)

That's definitively hot!
Part of the working heat is dissipated through the keyboard, is there no need to cut some airflow slits on the sides?
I am wondering if it is possible to cook an egg on the screen...

screen doesn't get noticeably hot, but i am running the fan flat out as with the eee overclocked to 972mhz the cpu temp gets kinda hot (up to 60 degrees!) the air coming out of the vent is bloody hot!, i have to pull it all apart again to sort out some issues (webcam has disapeared and the speakers dont work, although now that i think about it the usb hub is right over the cpu) and to finish up the cosmetics, i might add in some copper heatspreaders between the CPU/NB chips and the EM shield to help out with the temps

ended up putting the guts of this tablet into an un-hacked 701 housing i had and sold it, bought a **wont say manufacturer** **wont say model** netbook to hack into a more grown up tablet since it has the best silhouette and shape for this sort of thing, and all i can say is DAMN i was surprised how small it is compared to my 1000HD (same size screen) , but for anyone else following the 701 tablet hacking path i can give this bit of advise, its much easier to rotate the LCD panel 180 degrees inside the lid (you have to do some dremeling and move the webcam up 5mm, so the screen can move 5mm up and around 6 to the left, mount the inverter where the touchpad used to be (under the upper housing now behind the webcam) this results in you NOT having to extend the screen cable which is very well worth the effort as i ended up damaging mine, one of the data lines was shot so the colour black? was a funny green colour : (. i had lots of dramas on this build but it was fun none the less
