I hate nothing more than being away from my home office and finding I’ve left a critical spreadsheet or document half way around the country. 
Sure, I can get it emailed but that just wastes time and if the file’s too big odds are it gets rejected.

I’ve been a ‘road warrior’ for 5 years now and though I’m not highly technical I’ve tried a number of remote access solutions to overcome ‘on the move file sharing’.  I’ve tested Google Docs, but this requires that Google hosts all your files, so it’s not really a great solution as most of my images and docs are stored locally.  Both GoToMeeting and Citrix work, but they’re pricey and cumbersome to use.

WebPoint VPN has an odd name but it’s hands down the easiest Remote Access app I’ve ever used.  I signed up for the free trial, installed the software on my home pc and within 20 minutes I was able to access my home network.
It works perfectly with Vista & Windows 7, which is very cool!  It’s also got a great feature that it enables you to access any other connected pc in your network. 
You can run applications, like Citrix, but it’s faster and definitely easier to connect.
You can even remote connect via the web.  One caveat – it doesn’t play well with Mac.  Try it free before you buy.
