• More RAM.  Mine came with 1gb of RAM, but I have added a second GB (and voided my warranty)
• Blue Tooth: I have a blue tooth usb stick but built-in would have been nice.
• Bigger battery:  OK, I was cheap and save $20 by getting my notebook with a 3-cell, but I paid $80 to get a second 6-cell battery which gives me about 4 hours on the fly (more when you include sleep mode while travelling between places).

• STICKIES: My favorite program (and it is cool on desktops as well as laptops) is called Stickies.  While Windows 7 has a built in sticky note program, this freeware program called Stickies is much better.  Think of it as post-its on your computer desktop that don't fall off.  Enough said?
• EZOUTLOOKSYNC PRO:  Running two or more computers can be a real challenge where email is conserned.  If you use Outlook then this can cause some of your mail to download to one computer but not the other.  EZOutlookSync Pro ($59.95) allows me to quickly synchronize mail on my three computers with no loss of mail or calendar events.  They have cheaper version but the extra $20 is worth for the huge performance increase.
• MY LOCKBOX: This is a great program to keep files on your laptop that you don't want others to see (especially if you leave your laptop someplace you didn't want to leave it at).  This FREE program allows you to create an encrypted folder than can only be accessed via a password.  Windows 7 has it's own BitLocker encryption program, but that is available only in the Ultimate edition.
• TEAMVIEWER: For years I have used GotoMyPC to remotely connect to my desktop computer while I am on the road.  It has great security but it costs money ($20 per month).  While TeamViewer does not have as many features, it is very functional and free and accomplishes the same thing.  Designed to allow someone to take remote control of your computer to "fix things" or transfer files over the internet, it also has the ability for a user to show his/her desktop to someone else (they call it "presentation" mode: look at my spreadsheet type of thing).  It is also modular so you can send someone the small host version which does not even require installation: it runs "as is").
• SYNCTOY:  SyncToy is a freebie from Microsoft that allows you to synchronize file folders between two computers.  This is a must for people who use more than one computer, and this program is as good as some pay versions I have seen.  Fast and simple to use.
• ACRONIS TRUE IMAGE HOME 2009:  Netbooks are small and all notebooks are in danger of data loss due to hard drive failure.  Nothing better than having an image backup at the ready.  At $40 this is probably the best backup program out there.
