... as opposed to me or what I carry when I go on a business trip

- Laptop: my work laptop is a Lenovo X61 and I love it. It is relatively small despite the large battery for the extra power and works as a touchpad which is great for reviewing Powerpoints.

- Laptop accessories: only my large Lenovo branded mouse. I know I should have something better and/or smaller, but for someone who actively used that red dot in the middle of the keyboard as an alternative to a mouse for such a long time, this is a start.

- Mobile email: I use my Blackberry Bold. Although I am not a full crackberry user, I have been using different versions of the BB (this is my 4th to be precise) for more than 4 years. The Bold is the best: the experience is perfect for email, checking attachments on the go, instant messaging... and even knowing where you are (with A-GPS facility), some easy/low quality snapshots and listening to music. Not an iPhone/iPod killer, but decent enough to listen to some music when not on a call or when the in-flight entertainment is boring or "deja vu". I have recently toyed with the Blackberry Storm and am not convinced this will be a normal QWERTY keyboard phone-killer.

- Mobile voice, texting and browsing: given that my mobile phone collection is currently just above 80, I like switching phones quite regularly but there are a couple of rules:
1) I never ever use the Blackberry as my only phone - today is structural as living in China I use a Blackberry with an American SIM and only have contracted a data pricing scheme; in the past, I had bad experiences with voice on Blackberry, but am assured they have been solved.

2) I always bring a back-up phone with me in case the main one runs out of battery while in a car or running at the airport.

3) Given I am becoming more lazy and only want to carry a maximum of 2 mobile chargers (and the Blackberry already counts for one), the back-up phone will typically be the same brand as the main one or at least the same charger type (how nice is mini-USB charging, hey?).

4) If going for a longer trip (more than 3 nights), I almost always take of my favorites "at the time". Currently these are the iPhone 3G which has most of my non-pro (or attempted pro) pictures and music or the HTC/Google/T-mobile G1/G-Dream or whatever is called these days, for accessing all my Google info (email, calendar which I use for personal appointments, etc). Unfortunately these two phones lead me to stronger usage and... you guessed it... to shorter battery life.

5) When not traveling to Korea or Japan (and not in absolute need of 3G), I take as a back-up one of my "road warrior" phones which last and last and last. My recent favorite is the Philips X500, but most of the Nokia 1xxx series are also very good, as well as the Sony Ericsson J110i or J120i. For "3G-oblige" situations, the Sony Ericsson K610i is a surprising good choice.

- Mobile data: I do not carry a data card with me as I think it's a waste given all the phones I have with modem and HSDPA capabilities. I don't use the Blackberry for this and since I don't want to carry all the applications for PC connectivity under the sun or some players don't support tethering I leave the G1 and iPhone 3G at home, if I anticipate I will need cellular data connectivity. My preference is typically for Nokias or Sony Ericssons as I always their PC software installed on my laptop.

- Other gadgets and accessories: I have several bluetooth devices and my favourite is the Sony Ericsson HBH-DS980, since it is quite comfortable to put around your neck, is stereo and the quality is typically good. The Jawbone hasn't impressed me and the Samsung WEP 410 is great, but is so small that I am always afraid to lose it. I do carry wired headphones once in a while when I get fed up of having to charge the bluetooth ones. I always carry a USB to mini USB cable as it works on many of the phone I own including on the ever present Blackberry. I sometimes carry other cables in particular if I have a Sony Ericsson with me and want to access data on the PC through it. I also use a Jabra headset for my company VoIP system through my laptop - cost rationalization oblige.

- The ones that are no longer: my iPods have lost their place in my luggage, having been replaced by the Bold or the iPhone at times.
