Essential travel kit: my Garmin Edge 605

Without which I would be literally lost.  Now that I've discovered that I can actually type in addresses and search for local museums and get directed there it's functionality for me has greatly increased.  The only problem?  Garmin has recently brought out the new Edge 800, touch screen, faster, lighter & better looking....

vs the new Garmin Edge 800

More seriously though the things that bug me about the 605:  it can be a bit slow to find satellites
it's way too slow in recalculating routes.
There were only major roads on the GPS before I purchased the Europe NT map set, so do consider the approx £80 of the map cost as part of the package cost when contemplating purchase of this GPS.  I did consider getting just the UK maps, but I have used everywhere from Sweden, Finland, Norway, Denmark, France, Germany and I wouldn't be without it.  Of course with only basic software I had the impression that the machine ran faster.  I bought the maps in the CD format rather than SD card.  I'm not sure if the SD would have been faster because it's not on the hardware, but with the CD I can plan routes on my computer (which I never do) and I could also just put one country on the GPS at a time if I were organised.
