I am using HP Compaq tc4200 tablet from last three years and I am really satisfied with the performance that it gives.
The impression you’ll get when you first get your hands on the TC4200 is "solid", "compact" and "light". There is even more goodness on the inside. This Tablet PC is one of the first to feature Intel’s third generation of Centrino technology dubbed "Sonoma". Yes, deep down the TC4200 Tablet PC has got "guts". Better yet, you won’t find the aging Intel 845/855 chipset with(ugh, it makes me shudder to think about it) "Intel Extreme Graphics" technology. Instead the TC4200 has the MUCH improved Intel 915 chipset that incorporates "Intel Graphics Media Accelerator" graphics technology.
Basic Specs(Model that I use):
OS - Windows XP Tablet PC Edition 2005
Intel Pentium M 740(1.73GHz, 2MB L2 Cache, 533MHz FSB)
12.1"(1024 x 768) display
40GB, 5400RPM Hard Drive
512MB DDR2 SDRAM
No Optical Drive
Lithium Ion Battery(6 cell/ 52Wh)
Ports: RGB(monitor) port, TV-out(S-Video), 3 USB(2.0), External Mic jack, Headphone jack, RJ-45 LAN port, RJ-11 modem port, docking connector
Intel Graphics Media Accelerator - up to 128MB Dynamically Shared
Intel PRO/Wireless 2200BG(802.11b/g)
This model is really compact, durable and Solid, the TC4200 feels exquisitely durable with the lid closed, open or when folded down into "tablet mode".
The rotating display hinge has a "lasting" feel. The entire unit is constructed of strong black and charcoal plastics, giving the TC4200 a professional appearance with a basic, yet sleek style. HP states that a special "scratch-resistant, in-mold lamination" is used to keep the unit "looking newer longer". Also included is a spill-resistant keyboard and shock mounted hard drive.
One last thing to mention in regards to the design; there is no uncomfortable heat blasting out of the vents, nor do the hand rests or the base get unpleasantly hot. The only time I noticed any heat issue is when the battery is in mid charge. Luckily this time frame is quite short and should be the only time a user might skip the use of the TC4200 in "slate mode" or resting it on the lap.
