So in the link below it states Kingston released the 4GB DDR2-667 Module (1 piece) for a whopping 531 USD...wow...
Anyone have some spare change lying around..lol...
I know only 3 GB can be used for 32 bit XP and Vista....but anyone taking the plunge???
Maybe Kingston can send Kevin or James some test samples !!! (and they could tell us what improvements they see)

Like Kingston did for Keith Combs here: http://blogs.technet.com/keithcombs/archive/2008/06/04/my-lenovo-thinkpad-t61p-now-has-8gb-of-ram.aspx

here is the link to the module in Kingstons shop: http://shop.kingston.com/partsinfo.asp?promo=PRCGRBR&ktcpartno=KTL-TP667/4G

On a unrelated note.....Has anyone tried the diNOVO mini on their Q1UP..?? Does it work?? Impressive keyboard..(backlight also)..
also if anyone wants to help me upgrade my Q1UP..(I only have 1 GB now..looking to get 2GB.) let me know. I have seen Kevin's video..and wow that seemed difficult....!!! I would def. break something for sure if i tired..send me a PM k.

I can confirm that Logitech's dinovo mini keyboard works well with the Q1UP.  It's a wonderful little gadget!

Another question I had...was..Can bluetooth handle multiple pairings? Like could I pair the dinovo, a headset, and a bluetooth gps device???All at the same time??

Yes, bluetooth can handle multiple pairings. At the moment, I have bluetooth speakers, a keyboard, mouse, and my phone all paired to my q1up

As for, the 4gb sodimm, I don't think its worth the price considering that you won't be using all 4gbs. Might as well just buy an SSD for that price
