I'm about to go on year + world run myself. I decided on the N800 because of 2x sdhc slots. Also the all metal construction make it more robust. The onscreen keyboard works well. I picked up 6 16 gb sdhc cards for photobank, media storage, ebook. I have a bluetooth high sensitivity gps. Maemo mapper is excellent and I installed Kde to print to .pdf, any onlne travel guides. For my computing needs I have: 1. Nokia N800 2. 6 x 16 gb sdhc flash cards 3. extra oem battery 4. external battery charger, works with same battery for fenix led flashlight 5. Oncourse bluetooth gps 6. battery charger w 12v cigarette charger/ac adapters 7. light weight solar panel (8 oz.) w female cigarette plug 8. set of rechargeable cr123 lithium batteries 1000 ma each 9. ultralight powered usb hub (radio shack) 10. various modded cables, usb to camera, usb extension, mini usb to standard usb female 11. Boxwave usb, cigarette/us 110/220 plug charger 12. international plug adapter 13. mini power strip 14. light bulb outlet adapter Trying to keep this kit under 2 1/2 lbs. I'll post pics and links if you want. This set up is ultralight. I have 50 gb of media, 200 movies, wiki offline through sdict, various ebook collections and Kde environment with kde office. Still thinking of porting windows 95 for my ancient quickbooks. I'll be scanning in a mountaineering, wilderness medicine book to .pdf. This setup is the lightest and cheapest fairly full featured portable computing solution. The N800 is lighter than most windows umpc charging bricks. Where are you off to?
