Having the Ethernet port at the back of the laptop is worthy of extra comment. This is so much better than having it on the side, where a thick Ethernet cable will inevitably get in the way of your mouse, UBS Flash drives and so on.

Who says skinny sub-notebooks can't have optical drives?
Lenovo has come up trumps with wireless connectivity so the X300 packs Gigabit Ethernet, 802.11n and Bluetooth. You won’t find a modem port next to the Ethernet as Lenovo has gone for state-of-the-art technology: there's a Sierra MC8775 HSDPA 3G modem inside the laptop with a SIM card slot under the battery.

All the wireless options you could want or need
There’s a touch of next-gen technology too as Lenovo tells us that the X300 is ready to support WiMax "when it becomes available", which rather suggests that a Bios update may reveal new wonders in a year or two.
Verdict
The ThinkPad X300 is an expensive piece of kit but it’s a superb laptop that is well worth the asking price. Yes, it costs the best part of two grand. Yes, that is a very high price, but you really ought to get your hands on an X300 for a test drive. If you do, you won't want anything else.

COMMENTS
OMG, a dub-notebook article that's not written by Tony Smith!!!
Where is he and what have you done with him?
A few things.
First, lauding IBM for "catching up" with a widescreen display? Having recently been given a Dell with such I *really* miss my old 4:3 HP. Same screen width, less height=less screen, the resolution hike doesn't compensate at all. Until documents start being produced in A4 landscape by default rather than portrait, widescreen display will be a hindrance rather than a help on work machines. Even code tends to be long and narrow FFS!
Secondly, "......what it will be like when we all drive electric cars and the background noise in our towns and cities drops to a whisper." The answer to this one is "Bloody dangerous!". I came perilously close to getting "Prius'd" the other day when one snuck up behind me in stealth mode. You don't realise how much you rely on your hearing for threat detection until some SOB invents a way of circumventing it.
Finally, defragmentation. Take a well-used XP box and install a quality defrag product. Now run a full on and offline defrag including the MFT and metadata. Once complete check out the performance hike. I was utterly gobsmacked, and this was on a machine regularly defragged with conventional weapons. NTFS doesn't need defragging in much the same way as computers don't need electricity (i.e. you can do your computing on a hand-cranked Babbage engine, but it ain't going to be quick). Still, maybe that's all fixed in Vista........(not holding breath).
sub-notebook?
subs start with much smaller formfactor... eg 12" screen. its not all about the thickness of the device...thats an incorrect view spouted by Apple marketing. Toshiba Libretto, Asus Eee900, old classico Apple 12" powerbook... these are all sub-notebook.
notebook is 13.3 to 14" screens
