Dan,
First, I suggest you have a look in the (famous!)
ltwbook with the full title: "Personal Systems Reference, Lenovo ThinkPad Notebooks, 2005 to present - withdrawn (December 2006 - Version 316)". Therein, you will find specifications on the most recent T4x models; both T41/p's, T42/p's, and T43/p's, and there you will get a better picture of what resolutions/sizes etc are (/were!) available. Links to more specifications on (older) Thinkpads can be found in the thread
T4X specs.
All T42/p's are now out of production (since 2005, I believe), and in my belief you will
not be able to find any new in stock in any shops. But - now it is soon Christmas, so I am of course going to give you a... very nice
Christmas present... taa-daa!

If you (immediately!!) turn to a very interesting item currently at auction at the US eBay-site -->
here (ending in 1 day and 7 hours hours from
NOW) or the one
here (ending in 7 hours from
NOW) then you can start dreaming of having a
brand NEW 14.1" SXGA+ T42p! If you want to have a look within Europe (where chances are very small and prices are very high!), you should check the German ThinkPad user-community
ThinkPad forum.de (see their "Marktplatz"). If you intend to bid on the USA eBay, contact the seller first and say that you intend to bid... otherwise you might risk to be "banned" from bidding, since you are outside of USA. If the seller won't agree to letting you bid, immediately go to the
Marketplace of this forum, and ask if someone in the USA is willing to bid on behalf of you. There are SO many extremely kind and helpful, totally trustworthy members there, so personally I would have zero problem of transferring some say $500 pre-payment to a forum-friend (in the USA) who could then bid on behalf of you. Just a suggestion, if you don't know anybody in the USA who can jump in right now and who are also having a good eBay-reputation and will accept to bid on behalf of you. If I were in the USA, I would be happy to help - but I am very much outside, like you!
I have been following T42/p auctions at eBay for quite a while, and my guess is that this NEW (!!) T42p will (most likely) not go much above $ 600. Add to this the cost of shipping this item to the UK (probably approx. $50) and the VAT/customs duty you need to pay upon import into the UK (how much? about 20 %?), and then still this is absolutely a very good deal. You need to check if these units are still covered by warranty - is so, the warranty can be extended for two more years for about $150 (you can read about where/how in the thread
FS Flexview heaven T60P and T42P's - see the post of Sun Nov 25, 2007 1:41 pm).
But... if I were you (I know that I am not!), I would rather go for one of the 15" UXGA/FlexView T42p's.. they are a bit bigger, thus slightly heavier and consume slightly more power... but the FlexView/IPS display... aaah, once you have owned one, you find it hard to go back to some XGA or other non-FlexView type!
Well, I'll leave it for now (I could continue for long, as I am a 15" UXGA/FlexView T42p-addict, which you may already have guessed!), but if you shall have a chance to consider the above, truly outstanding eBay Christmas-suggestion, I better post this reply right now.
Feel free to ask, if you want more Christmas presents!
Best regards,
Johan
