Whatever Google is doing to fight web search spam does not seem too effective.
Here are search results for "ex-03 usb phone" query:
Custom uninstallers for very niche application (and I'm not even searching for application)? Shit me not. Four out of ten top search result here are domains with algorithmically generated content distributing highly suspicious "uninstallers".
It gets worse: in my personalized (that is when I'm logged in) search results another two similar domains appear in first page thus giving more spam than real content. For comparison: none of these domains appear in top bing, yahoo or yandex search results.
Google search has spam reporting (https://www.google.com/webmasters/tools/spamreportform?hl=en) although my reports here are either ignored or sitting in queue for quite a long time (almost two weeks at the moment).

- solid construction; slightly weaker points are display twisting resistance and palmrest plastic (although metal chassis is directly under palmrest, so this is only minor crackling when pushing at right side)
- mat finish and probably very high wear resistance (plain black plastics with no coating of any kind)
- still perfectly fine performance for most home/office uses; inexpensive to upgrade with DDR3
- low temperature (exhaust at both back and left side) and fan noise (although fan seems to be active all the time)
- relatively small touchpad (I've disabled it completely in BIOS as it often generated random clicks for me when typing)
- display proportions: 16:10
- decent WiFi range / antenna set
- great trackpoint (comparing with my previous Dell D600)
- poor USB port placement - all three are placed on left side near the front and also susceptible to mechanical damage - there are numerous reports of broken ports and they are quite expensive to replace
- some noises from switching on-board voltage converters (quite disturbing at first, although I stopped noticing it after some time); surprisingly I haven't hear them when working on second R500 with T5870 processor - it might be individual issue
- bad speaker sound quality at higher volume (resonating at some frequencies, especially right one - fixed partially by putting foam layer between speaker and optical drive)
- quite fragile when it comes to fluids - that's how my first R500 died; it was just a small amount of water spilled at left bottom keyboard area, but there is nothing to prevent fluids from entering through the crack between palmrest and top bevel and DC/DC converters are very close to this area
Update. While R500 is definitely not resistant to water it turns out mine has survived. At first, after days of drying, laptop was reacting to power switch but screen was blank with inactive backlight. It started working again after resetting CMOS by removing backup cell (well, pity I got this idea very, late buying T500 in meantime).

Pentagram P6391
Router with 4 LAN + 1 WAN ethernet ports and WiFi based on Atheros AR2318.
On the right: second antenna.
HY57V641620: 8MB SDRAM, 3.3V.
Marvell 88E6060 - low power ethernet switch with 5 independent PHYs, 6 independent MACs, auto crossover, lookup memory for 1024 MAC addresses. Interestingly, each PHY supports technology called Virtual Circuit Tester, according to datasheet able to locate cable problems (open/short cable) with 1 meter precision, based on Time Domain Reflectometry. Chip can be configured with MDIO interface or with external serial EEPROM.
Classic DC/DC converter with 34063 and some external transistor in SO-8 package. There is rectifying bridge on board, router is intended to be powered with AC voltage.
25L1605 SPI Flash memory, 2MB, 32 sectors 64kB each, 10k P/E cycles, 3.3V.
